At the Royal Mail you are sometimes made to come into work even when you are sick or injured, on threat of dismissal. It’s called an ‘Attendance Procedure’. They monitor your attendance. If you are off work for sickness or injury too many times, or for too long, you are given a Stage 1 warning. If you go over the limit a second time while still on the Stage 1 warning, you are given a Stage 2 warning. If you exceed the limit for a third time you are given a Stage 3 warning and threatened with dismissal. The limits are: either three absences in the space of a year, or one absence of three weeks or more. This is whether or not you are actually ill. All illnesses are assumed to be genuine, but all illnesses, no matter how desperate, also count towards your warnings. They don’t take any mitigating circumstances into account.
