Refusal of work is behavior which refuses to adapt to regular employment.

As actual behavior, with or without a political or philosophical program, it has been practiced by various subcultures and individuals. Radical political positions have openly advocated refusal of work. From within Marxism it has been advocated by Paul Lafargue and the Italian workerist/autonomists (e.g. Antonio Negri, Mario Tronti), the French ultra-left (e.g. Échanges et Mouvement); and within anarchism (especially Bob Black and the post-left anarchy tendency).

Paruresis ( ) is a type of phobia in which the sufferer is unable to urinate in the real or imaginary presence of others, such as in a public restroom. The analogous condition that affects bowel movement is called parcopresis.

Counterdependency is the state of refusal of attachment, the denial of personal need and dependency, and may extend to the omnipotence and refusal of dialogue found in destructive narcissism, for example.

The roots of counterdependency can be found in the age-appropriate negativism of two-year-olds and teens, where it serves the temporary purpose of distancing one from the parental figure[s]. As Selma Fraiberg put it, the two-year-old "says 'no' with splendid authority to almost any question addressed to him...as if he establishes his independence, his separateness from his mother, by being opposite". Where the mother has difficulty accepting the child's need for active distancing, the child may remain stuck in the counterdependent phase of development because of developmental trauma.

In similar fashion, the teenager needs to be able to establish the fact of their separate mind to their parents, even if only through a sustained state of cold rejection; and again unresolved adolescent issues can lead to a mechanical counterdependence and unruly assertiveness in later life.

There can be serious difficulties with workplace drug testing where observed urine samples are insisted upon, if the testing regime does not recognise and cater for the condition. In the UK, employees have a general right not to be unfairly dismissed, and so have an arguable defence if this arises, but this is not the case everywhere.

There is growing evidence to suggest that some drug testing authorities find paruresis a nuisance, and some implement "shy bladder procedures" which pay no more than lip service to the condition, and where there is no evidence that they have conducted any real research into the matter. In the U.S. Bureau of Prisons, the Code of Federal Regulations provides that "An inmate is presumed to be unwilling if the inmate fails to provide a urine sample within the allotted time period. An inmate may rebut this presumption during the disciplinary process." Although U.S. courts have ruled that failure to treat properly diagnosed paruresis might violate prisoner's constitutional rights, the courts have also "routinely rejected suspicious or unsubstantiated attempts to invoke it in defense of failure to complete drug testing," particularly when there were no medical record or physician testimony to back up the claim of paruresis. The International Paruresis Association stresses the importance of medical documentation of one's condition since "[t]he person who is unable to produce a urine sample is presumed guilty in the absence of any evidence." Some prisons have offered the use of a "dry cell"—i.e., a cell with no toilet facilities, but only a container for the prisoner's waste—as an accommodation to inmates who are hindered by paruresis from providing an observed urine sample.

FBOP Program Statement 6060.08 states, "Ordinarily, an inmate is expected to provide a urine sample within two hours of the request, but the Captain (or Lieutenant) may extend the time if warranted by specific situations (for example, the inmate has a documented medical or psychological problem, is dehydrated, etc.). Staff may consider supervising indirectly an inmate who claims to be willing but unable to provide a urine sample under direct visual supervision. For example, this might be accomplished by allowing the inmate to provide the sample in a secure, dry room after a thorough search has been made of both the inmate and the room." At least six state prison systems — Florida, Massachusetts, Maryland, Michigan, New York and Tennessee — have modified their drug testing regulations to provide accommodations for prisoners with paruresis.

Per the "Handbook of Correctional Mental Health", "No definitive or objective test is available to confirm or refute the presence of paruresis. The absence of prior treatment or the ability to void in some social situations but not in others does not rule it out. Although modalities associated with the treatment of social phobias help some individuals, no universally effective medication or other treatment exists. Coercive interventions, such as forcing fluids while observing a person with paruresis, are ineffective and can cause serious medical complications. Alternatives to observed urine specimen collection for individuals who self-report paruresis include unobserved collections in a dry room, testing of hair specimens, sweat testing with a patch, and blood testing ('Test for Drugs of Abuse' 2002). These alternatives preclude the need for futile attempts to differentiate inmates with true paruresis from those who fabricate complaints."

Digital hoarding (also known as e-hoarding) is excessive acquisition and reluctance to delete electronic material no longer valuable to the user. The behavior includes the mass storage of digital artifacts and the retainment of unnecessary or irrelevant electronic data. The term is increasingly common in pop culture, used to describe the habitual characteristics of compulsive hoarding, but in cyberspace. As with physical space in which excess items are described as "clutter" or "junk," excess digital media is often referred to as "digital clutter."

International human rights law does not recognize the refusal of work or right not to work by itself except the right to strike. However the Abolition of Forced Labour Convention adopted by International Labour Organization in 1957 prohibits all forms of forced labour.

Disability fraud is the receipt of payment(s) intended for the disabled from a government agency or private insurance company by one who should not be receiving them, or the receipt of a higher amount than one who is entitled to them should be receiving. There are various acts that may constitute disability fraud. These include feigning a medical problem in order to be declared disabled, exaggeration of an existing medical problem that potentially can but in reality does not render the person disabled, continuing to receive payments after having recovered from a medical problem, or continuing to receive payments while working (usually unreported) above the allowable level for those receiving the payments.

Disability fraud can be harder to detect than other forms of fraud, as the majority of people receiving disability payments (at least 90%) do not use a wheelchair or walker, while at the same time, many people who need wheelchairs would not qualify for disability payments. Since most disabilities are "silent" (meaning that they cannot be seen by others), it is not easy to visually determine if a person receiving disability is not disabled. Such people are often able to perform physical activities, but have some other underlying cause of their disability. It is therefore common for people to believe they must report a neighbor who they see, for example, climbing on the roof while collecting disability payments, but this is not always the case.

Meanwhile, true disability fraud cases exist, for which it is hard to determine the cause as being fraudulent. Often, the perpetrator claims to have a medical condition to be declared disabled. Some medical conditions are truly debilitating and make it impossible or difficult to work if one has them, but are hard to prove against one's own word that one does not have them. These include chronic fatigue syndrome, chronic pain, or various mental disorders. Even if one with one of them is viewed engaging in some other "work-like" activity not for pay, they may have difficulty holding a job.

It is possible that the illegal recipient of the disability payments is not truly disabled, and may have a case of work aversion, which in many countries is not alone considered a valid reason for being declared disabled, or the person may otherwise lack a work ethic. Others who are receiving payments are actually working, but are not reporting their employment and collecting their income in a manner that cannot easily be detected.

Disability fraud can result in denial of future benefits as well as criminal prosecution.

Digital hoarding stems from a variety of individual traits and habits, corporate conditions, and societal trends:

- Some individuals experience anxiety when faced with disposing of digital items, particularly if they fear losing something important.

- Many digital hoarders don't know how to organize their digital content or aren't in the habit of doing so, and they lack a methodology for determining which content is worth keeping.

- Keeping all of one's digital files requires less time and effort than evaluating and deleting them.

- Many businesses rely on email correspondence for decision-making and formal approvals, so employees are often careful to keep work emails in case they are needed to verify a decision later.

- Data storage devices are now so large and inexpensive that individuals and companies often do not feel the need to save data selectively.

- The widespread availability and rapid dissemination of open content on the Internet makes it easier for users to obtain digital media, which can accumulate more quickly than ever.

- Since digital media do not take up physical space, they're less likely to be perceived as clutter, and users can more easily forget the extent of what they own.

- Unlike many physical items, electronic content does not die or decay on its own; users must consciously choose to delete it.

Education is the most common treatment, although psychotherapy, including cognitive-behavioral therapy, is indicated when the fear becomes so severe as to cause dysfunction for the individual who suffers from the phobia.

Certain children who are particularly attached to their mother or other family figure due to separation anxiety and/or attachment theory often suffer the onset early, in pre-school, crèche or before school starts.

School phobia is diagnosed primarily through questionnaires and interviews with doctors. Other methods like observation have not proven to be as useful. This is partly because (school) anxiety is an internal phenomenon. An example of a modern multidimensional questionnaire is the "Differential Power Anxiety Inventory 'approach, with twelve scales to diagnose four different areas: anxiety-inducing conditions, manifestations, coping strategies and stabilization forms."

- Cognitive and lifestyle exploration

- 'School Phobia Test' (SAT)

- 'Anxiety questionnaire for students', (AFS)

The United States Social Security Administration accepts reports from the public for the following types of fraud:

- Applicants who state they are not married when they are. Those receiving Supplemental Security Income (SSI) can have their benefits reduced by their spouse's income and assets, so some applicants may wish to hide the existence, income, or assets of their spouse.

- Claims of blindness. In particular, the Social Security Administration is concerned about those who declare they are blind and unable to drive, but are later found to be in possession of a driver's license and are observed (legally) operating a motor vehicle.

- Unreported income. Some types of income that often go unreported are from renting out a portion of one's home, or from an insurance policy.

- Employment changes, in a person who was not working at the time they applied for and started to receive benefits, but has since returned to work.

- A person who is living in an institution, such as a long-term care facility or a prison.

- A person who is the legal custodian (representative payee) of a disabled person's money spending it on some expense other than that of the disabled person.

- A person who cashes the checks of a deceased person.

Mageirocophobia is derived from the classical Greek noun mágeiros (μάγειρος), which means chef or butcher.

While sick building syndrome (SBS) encompasses a multitude of non-specific symptoms, building-related illness (BRI) comprises specific, diagnosable symptoms caused by certain agents (chemicals, bacteria, fungi, etc.). These can typically be identified, measured, and quantified. There are usually 4 causal agents in BRI; 1.) Immunologic, 2.) Infectious, 3.) toxic, and 4.) irritant. For instance, Legionnaire's disease, usually caused by "Legionella pneumophila", involves a specific organism which could be ascertained through clinical findings as the source of contamination within a building. SBS does not have any known cure; alleviation consists of removing the affected person from the building associated with non-specific symptoms. BRI, on the other hand, utilizes treatment appropriate for the contaminant identified within the building (e.g., antibiotics for Legionnaire's disease). In most cases, simply improving the indoor air quality (IAQ) of a particular building will attenuate, or even eliminate, the acute symptoms of SBS, while removal of the source contaminant would prove more effective for a specific illness, as in the case of BRI. Building-Related Illness is vital to the overall understanding of Sick Building Syndrome because BRI illustrates a causal path to infection, theoretically. Office BRI may more likely than not be explained by three events: “Wide range in the threshold of response in any population (susceptibility), a spectrum of response to any given agent, or variability in exposure within large office buildings." Isolating any one of the three aspects of office BRI can be a great challenge, which is why those who find themselves with BRI should take three steps, history, examinations, and interventions. History describes the action of continually monitoring and recording the health of workers experiencing BRI, as well as obtaining records of previous building alterations or related activity. Examinations go hand in hand with monitoring employee health. This step is done by physically examining the entire workspace and evaluating possible threats to health status among employees. Interventions follow accordingly based off the results of the Examination and History report.

School refusal is the refusal to attend school due to emotional distress. School refusal differs from truancy in that children with school refusal feel anxiety or fear towards school, whereas truant children generally have no feelings of fear towards school, often feeling angry or bored with it instead. Children's Hospital Boston provides a chart showing the difference between the school refusal and truancy.

Besides calling it School Refusal, it can also be called schooliophobia, school phobia was coined by a former editor. Schooliophobia is coined as all phobias are derived from Greek. In such cases, School in Greek is σχοείο. The term "school refusal" was coined to reflect that children have problems attending school for a variety of different reasons and these reasons might not be the expression of a true phobia, such as separation or social anxiety.

In today’s world using computers is a necessity for the majority of people but not many people actually consider the medical consequences that working with computers can cause, such as damaged eyesight, bad posture, arthritis in fingers and computer stress injuries that can be caused by sitting in one position for a prolonged period of time. The above problems are more commonly associated with old age but due to many factors such as poor component design, proximity of the user to the screen and an excess of consecutive working hours mean that the above problems can feature in both young and old computer users. This is an extremely important issue as computers become more important in every corner of employment the medical effects caused by them will elevate unless sufficient research is performed and time is dedicated into eliminating and reducing these problems as much as possible. It is estimated that today at least 75% of all jobs involve some level of computer use; this means three-quarters of the workforce are being exposed to numerous health problems, the same can be said of students and educators who do not go through any day without access to a computer for academic work. The figure for people working with and using computers recreationally is to increase considerably in the coming years so it is crucially important that these problems are identified and resolved sooner rather than later in an effort to reduce if not eradicate these problems.

Notable physical medical problems that can arise from using computers include Carpal Tunnel Syndrome, Computer Vision Syndrome, and Musculoskeletal problems.

The mental health community does not recognize work aversion as an illness or disease and therefore no medically recognized treatments exist. Those attempting to treat work aversion as an illness may use psychotherapy, counseling, medication, or some more unusual forms of treatment.

In the case where the person has not worked for a while due to a workplace injury, work-hardening can be used to build strength. The person works for a brief period of time in the first week, such as two hours per day and increases the amount of work each week until full-time hours are reached.

Work aversion (or aversion to work) is the state of avoiding or not wanting to work or be employed, or the extreme preference of leisure as opposed to work. It can be attributed to laziness, boredom or burnout. Work aversion is not a recognized psychological disorder in the DSM-IV.

Some studies have shown a small difference between genders, with women having slightly higher reports of SBS symptoms compared to men. However, many other studies have shown an even higher difference in the report of sick building syndrome symptoms in women compared to men. It is not entirely clear, however, if this is due to biological, social, or occupational factors.

A 2001 study published in the Journal Indoor Air 2001 gathered 1464 office-working participants to increase the scientific understanding of gender differences under the Sick Building Syndrome phenomenon. Using questionnaires, ergonomic investigations, building evaluations, as well as physical, biological, and chemical variables, the investigators obtained results that compare with past studies of SBS and gender. The study team found that across most test variables, prevalence rates were different in most areas, but there was also a deep stratification of working conditions between genders as well. For example, men’s workplace tend to be significantly larger and have all around better job characteristics. Secondly, there was a noticeable difference in reporting rates, finding that women have higher rates of reporting roughly 20% higher than men. This information was similar to that found in previous studies, indicating a potential difference in willingness to report.

There might be a gender difference in reporting rates of sick building syndrome because women tend to report more symptoms than men do. Along with this, some studies have found that women have a more responsive immune system and are more prone to mucosal dryness and facial erythema. Also, women are alleged by some to be more exposed to indoor environmental factors because they have a greater tendency to have clerical jobs, wherein they are exposed to unique office equipment and materials (example: blueprint machines), whereas men often have jobs based outside of offices.

Bibliomania is not to be confused with bibliophilia, which is the usual love of books and is not considered a clinical psychological disorder.

Other abnormal behaviours involving books include book-eating (bibliophagy), compulsive book-stealing (bibliokleptomania), and book-burying (bibliotaphy).

Felching is a sexual practice involving the act of orally sucking semen out of the anus of one's partner. The act of sucking semen out of a vagina is known as creampie eating.

Bibliomania can be a symptom of obsessive–compulsive disorder which involves the collecting or even hoarding of books to the point where social relations or health are damaged.

Ergophobia or ergasiophobia is an abnormal and persistent fear of (manual labor, non-manual labour, etc.) or finding employment. Ergophobia may also be a subset of either social phobia or performance anxiety. Sufferers of ergophobia experience undue anxiety about the workplace environment even though they realize their fear is irrational. Their fear may actually be a combination of fears, such as fear of failing at assigned tasks, speaking before groups at work (both of which are types of performance anxiety), socializing with co-workers (a type of social phobia), and other fears of emotional, psychological and/or physiological injuries.

The term "ergophobia" comes from the Greek "ergon" (work) and "phobos" (fear).

Elective mutism was defined as a refusal to speak in almost all social situations (despite normal ability to do so), while selective mutism is considered to be a "failure" to speak in specific situations and is strongly associated with social anxiety disorder. In contrast to selective mutism, someone who is electively mute may not speak in any situation, as is usually shown in books and movies. Elective mutism is often attributed to defiance or the effect of trauma.
