But I feel bad for my mum. She recently had an op (end of march), after which she has followed the procedure of doctors certificates and what she is supposed to do. However, her workplace seems to have breached the advice on the certification on two occasions. One, within in the very first week, where she was supposed to have been spending half her shift time at work, but this was upped before the week was out just to fit in line with their standard working week. The second, was a miscommunication and misunderstanding with another team leader, but on a managers choice of day off it gave her no choice but to stay behind 2 hours later. I'm pretty annoyed but there's nothing I can actually do/I have no right to do anything about it.
