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.

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."

It appears that paruresis involves a tightening of the sphincter and/or bladder neck due to a sympathetic nervous system response. The adrenaline rush that produces the involuntary nervous system response probably has peripheral and central nervous system involvement. The internal urethral sphincter (smooth muscle tissue) or the external urethral sphincter (striated muscle), levator ani (especially the pubococcygeus) muscle area, or some combination of the above, may be involved. It is possible that there is an inhibition of the detrusor command through a reflex pathway as well. The pontine micturition center (Barrington's nucleus) also may be involved, as its inhibition results in relaxation of the detrusor and prevents the relaxation of the internal sphincter.

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.

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.

Mageirocophobia ("pronunciation": ˌmædʒaɪrɪk-a-pho-bee-a) is the fear of cooking. It is spectral and can take on several forms, although it is not considered severe enough for treatment unless a person is severely afraid or impacted. Most frequently, it is a common social anxiety disorder caused by negative reactions to common culinary mishaps, post-traumatic stress episodes from cooking or the fear of others' cooking for the phobic person that either prevents them from eating, eating only pre-prepared foods and snacks, or causes them to eat away or take away foods that can result in unhealthy diets associated with hypertension, obesity, and diabetes.

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

Symptoms of school refusal include the child saying they feel sick often, or waking up with a headache, stomachache, or sore throat. If the child stays home from school, these symptoms might go away, but come back the next morning before school. Additionally, children with school refusal may have crying spells or throw temper tantrums.

Warning signs of school refusal include frequent complaints about attending school, frequent tardiness or unexcused absences, absences on significant days (tests, speeches, physical education class), frequent requests to call or go home, excessive worrying about a parent when in school, frequent requests to go to the nurse’s office because of physical complaints, and crying about wanting to go home.

It is important for parents to keep trying to get their child to go back to school. The longer a child stays out of school, the harder it will be to return. However, it may be hard to accomplish as when forced they are prone to temper tantrums, crying spells, psychosomatic or panic symptoms and threats of self-harm. These problems quickly fade if the child is allowed to stay home.

Parents should take their child to the doctor, who will be able to rule out any illness that may be causing the problem. Parents should also talk to the child’s teacher or school counselor. Although school refusal is not a clinical disorder according to the "Diagnostic and Statistical Manual of Mental Disorders", Fourth Edition, it can be associated with several psychiatric disorders, including Separation Anxiety Disorder, Social Phobia, and Conduct Disorder. Therefore it is critical that youths who are school refusing receive a comprehensive evaluation by a mental health professional.

Whereas some cases of school refusal can be resolved by gradual re-introduction to the school environment, some others may need to be treated with some form of psychodynamic or cognitive-behaviour therapy. Some families have sought alternative education for school refusers which has also proved to be effective. In extreme cases, some form of medication is sometimes prescribed but none of these have stood out prominently as solutions to the problem.

A medical condition often mistaken for school refusal is delayed sleep phase syndrome (DSPS). DSPS is a circadian rhythm sleep disorder which is characterized by a chronic delayed sleep cycle.

The attempt to control by means of threats or pressure, the behaviour of the student, is also still in danger as external (extrinsic) motivation to undermine intrinsic motivation and a sense of self-control, self-worth and self-responsibility. Some social scientists and evaluaters view the condition as a pseudophobia.

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.

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.

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.

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.

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.

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).

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).

Work aversion usually occurs in persons who have previously been employed, and can have a variety of causes. These include:

- Boredom with work: Holding a boring job early in life can lead to the impression later that all work is boring.

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.

Computer-induced health problems can be an umbrella term for the various problems a computer user can develop from prolonged and incorrect computer use. A computer user may experience many physical health problems from using computers extensively over a prolonged period of time in an inefficient manner. The computer user may have poor etiquette when using peripherals, for example incorrect posture. Reportedly, excessive use of electronic screen media can have ill effects on mental health related to mood, cognition, and behavior, even to the point of hallucination.

Richard Weaver, in his work "Ideas Have Consequences", introduced the term “spoiled child psychology” in 1948. In 1989, Bruce McIntosh coined the term the "spoiled child syndrome". The syndrome is characterized by "excessive, self-centered, and immature behavior". It includes lack of consideration for other people, recurrent temper tantrums, an inability to handle the delay of gratification, demands for having one's own way, obstructiveness, and manipulation to get their way. McIntosh attributed the syndrome to "the failure of parents to enforce consistent, age-appropriate limits", but others, such as Aylward, note that temperament is probably a contributory factor. It is important to note that the temper tantrums are "recurrent". McIntosh observes that "many of the problem behaviors that cause parental concern are unrelated to spoiling as properly understood". Children may have occasional temper tantrums without them falling under the umbrella of "spoiled". Extreme cases of spoiled child syndrome, in contrast, will involve "frequent" temper tantrums, physical aggression, defiance, destructive behavior, and refusal to comply with even the simple demands of daily tasks. This can be similar to the profile of children diagnosed with Pathological Demand Avoidance, which is part of the autism spectrum.

A spoiled child, spoiled brat, or simply a brat is a derogatory term aimed at children who exhibit behavioral problems from being overindulged by their parents. Children and teens who are perceived as spoiled may be described as "overindulged", "grandiose", "narcissistic" or "egocentric-regressed". Perception is important to take into account, because when the child has a neurological condition such as autism, ADHD or intellectual disability, observers may judge them as "spoiled" without understanding the whole picture. There is no accepted scientific definition of what "spoiled" means, and professionals are often unwilling to use the label because it is considered vague and derogatory. Being spoiled is not recognized as a mental disorder in any of the medical manuals, such as the ICD-10 or the DSM-IV, or its successor, the DSM-5.

Human exposure to bioaerosols has been documented to give rise to a variety of adverse health effects. Building occupants complain of symptoms such as sensory irritation of the eyes, nose, or throat; neurotoxic or general health problems; skin irritation; nonspecific hypersensitivity reactions; infectious diseases; and odor and taste sensations. Exposure to poor lighting conditions has led to general malaise.

Extrinsic allergic alveolitis has been associated with the presence of fungi and bacteria in the moist air of residential houses and commercial offices. A very large 2017 Swedish study correlated several inflammatory diseases of the respiration tract with objective evidence of damp-caused damage in homes.

The WHO has classified the reported symptoms into broad categories, including: mucous membrane irritation (eye, nose, and throat irritation), neurotoxic effects (headaches, fatigue, and irritability), asthma and asthma-like symptoms (chest tightness and wheezing), skin dryness and irritation, gastrointestinal complaints and more.

Several sick occupants may report individual symptoms which do not appear to be connected. The key to discovery is the increased incidence of illnesses in general with onset or exacerbation within a fairly close time frame—usually within a period of weeks. In most cases, SBS symptoms will be relieved soon after the occupants leave the particular room or zone. However, there can be lingering effects of various neurotoxins, which may not clear up when the occupant leaves the building. In some cases—particularly in sensitive individuals—there can be long-term health effects.

Sick building syndrome (SBS) is a medical condition where people in a building suffer from symptoms of illness or feel unwell for no apparent reason. The symptoms tend to increase in severity with the time people spend in the building, and improve over time or even disappear when people are away from the building. The main identifying observation is an increased incidence of complaints of symptoms such as headache, eye, nose, and throat irritation, fatigue, and dizziness and nausea. These symptoms appear to be linked to time spent in a building, though no specific illness or cause can be identified. SBS is also used interchangeably with "building-related symptoms", which orients the name of the condition around patients rather than a "sick" building. A 1984 World Health Organization (WHO) report suggested up to 30% of new and remodeled buildings worldwide may be subject of complaints related to poor indoor air quality.

Sick building causes are frequently pinned down to flaws in the heating, ventilation, and air conditioning (HVAC) systems. However, there have been inconsistent findings on whether air conditioning systems result in SBS or not. Other causes have been attributed to contaminants produced by outgassing of some types of building materials, volatile organic compounds (VOC), molds (see mold health issues), improper exhaust ventilation of ozone (byproduct of some office machinery), light industrial chemicals used within, or lack of adequate fresh-air intake/air filtration (see Minimum efficiency reporting value).
