Working Flexibility and Culture

Absa has been offering limited flexibility for its Czech employees for several years now due to the nature of the cross-ocean team structures. It is up to each team to decide whether regular office visits are required, however generally after the first "getting to speed" period, if it's not stated otherwise, employees are not expected to visit offices on an everyday basis, though it is possible if the employee prefers to do so themselves. Absa values diversity and inclusion and works towards providing equal possibilities and a non-stress work environment for all its employees, supporting proper healthy work-life balance and respecting personal commitments. Details are to be discussed with the hiring manager personally.

Despite the hybrid working environment, Absa supports (but not enforces) regular in-person catch-ups and provides a perfect ground for them by organizing regular all-stuff nonformal events and, several times per year, bigger events such as Christmas and summer parties.
