This paper presents an ergonomic contribution and a detailed insight into the course of circadian rhythm disorders, i.e. the consequences that lead to disruption of normal circadian rhythm in humans, based on scientific research conducted by medical staff at a COVID county hospital in the Republic of Croatia. Business processes that take place in the organizational environment are mainly of a psycho - biomechanical and rhythmic nature, i.e. they appear in certain time intervals. Thus, for example, we monitor the phases of wakefulness and sleep, depending on the alternation of day and night, as well as a number of other changes that show cyclical repetition. The appearance of such time-defined changes is visible not only in the working environment but also at every organizational level of living beings. Circadian rhythm plays a very significant role in the life and work activities of humans. It determines daily life, and by knowing this cycloid rhythm, work obligations can, for example, be adjusted to the time of day when employees are in the zone of optimal concentration and maximum work productivity.
