In the article, personal festive celebrations of co-workers in a diachronic perspective are examined. The following occasions: birthdays, childbirth, marriage, funerals (the family life cycle), and employee employability, seniority or similar achievements and retirement (the working life cycle), are important for socialising with co-workers, for job satisfaction, and in the formation of an organisational culture. By analysing fieldwork data, we determine the intensity of the commemoration of these occasions in the studied areas.
