Fear of work: An abnormal and persistent fear of work. Sufferers of this fear 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 fear of failing at assigned tasks, fear of speaking before groups at work, or fear of socializing with co-workers.

Fear of work is termed "ergophobia," a word derived from the Greek "ergon" (work) and "phobos" (fear). "Ergo" is also used to form other English words, including "ergometer" (a device that measures the amount of work done by muscles) and "ergonomics" (an applied science that designs office equipment and furniture with the aim of maximizing functionality and improving worker comfort).
