Your COUNTING sick days. Sick days are generally not counted elsewhere. There are limitations on the number of consecutive days you can take without getting signed off by a doctor, but that’s it. Had one team member that got frequent migraines, and averaged about 1 sick day every two weeks. Good employee, just took a lot of sick leave. Questions were asked but because it was a valid reason nothing was done.
What you’re describing is 25 days off plus public holidays. Very normal.
