Most people do what they want, on their own time, away from work
Control freaks are often perfectionists defending themselves against their own inner vulnerabilities in the belief that if they are not in total control they risk exposing themselves once more to childhood angst. Such persons manipulate and pressure others to change so as to avoid having to change themselves, and use power over others to escape an inner emptiness. When a control freak's pattern is broken, “the Controller is left with a terrible feeling of powerlessness … But feeling their pain and fear brings them back to themselves”.
Control freaks appear to have some similarities to codependents, in the sense that the latters' fear of abandonment leads to attempts to control those they are dependent on. Recovery for them entails recognising that being a control freak helped paradoxically preserve codependency itself.
In terms of personality-type theory, control freaks are very much the Type A personality, driven by the need to dominate and control.
Obsessive–compulsive personality disorder
Obsessive–compulsive personality disorder (OCPD), also called anankastic personality disorder, is a personality disorder characterized by a pervasive pattern of preoccupation with orderliness, perfectionism, mental and interpersonal control and a need for power over one's environment, at the expense of flexibility, openness, and efficiency. It results in complete satisfaction after performing these rituals to the point of excluding leisure activities and friendships. Persons affected with this disorder may find it hard to relax, always feeling that time is running out for their activities and that more effort is needed to achieve their goals. They may plan their activities down to the minute—a manifestation of the compulsive tendency to keep control over their environment and to dislike unpredictable things as things they cannot control
