I have this stupid situation to which I don't know how to act accordingly. Last week i was on sick leave for 3 days and I forgot to bring in my sick note from doctor. Today i got paid my monthly salary which should have been smaller than usual because of the work days i skipped because I was ill. I have not talked about this with my employer and i actually don't know how to approach him with this situation.
Is this some kind of violation? What could be penalties because of this, could I got in some kind of problems? Have anyone been in this situation before, what could happen if I act like nothing is wrong and as if I was never sick? How should i approach my employer about this?
