Lots of people think anyone can work in a bar then they find out that it's not that easy. Or it was never their real job anyway. They do it in between their real jobs.I often wonder what happens to bar staff when a pub closes. They never re open with the same staff. There must be a lot of heartache there. People seem to lose their jobs quite regularly in the bar trade. Every job lost is a story waiting to be told. I look at other people losing their jobs and it doesn't register. But where do they go, what do they do, how do they feel?
You need to talk to whatever they call "human resources" where you live. You have a medical problem and they can't fire you for that. They will have to put you on leave and give you time to work it out. This is the best advice you're going to get this week.
