I worked in a restaurant, they would keep cutting my shifts the day before and not tell me about it so I would find out on my own and have to message the manager. This happened about four times over the course of a month. My frustrations grew so I handed in my three week notice. Come the Saturday, they ask if I can work the scheduled Sunday shift at a different venue and by this point, I’d had enough of being messed around and assumed it was because they were cutting another shift, so I messaged the manager saying ‘I couldn’t give a fuck, pass it on’
Come the next day, the manager said that shift was going to be the last day, apologies bla bla bla. He was just passing a message on from the owners and I kind of felt pretty bad for him because he looked really awkward.
Is this grounds for unfair dismissal? If so, what steps can I take?
