I'm a departmental manager in a 7 day a week industry (think hotel) as a result my team and I have our days off at random over all days of the week. This is not true of the GM and other upper management who do strictly Monday to Friday. I've had a full on week this week and done almost 60 hours over 6 days. I'm off Monday and Tuesday next week. After I'd already issued my rota, we were told there will be an undisclosed 'event' on Monday held over 2 sessions, 2.5 hours each session. Attendance at one of these sessions is 'mandatory' whether you are on the rota that day or not. They have not confirmed whether they will pay people to attend these sessions. I've told my team I will not be attending and it is up to them whether they attend if it's their day off, I would be a hypocrite to insist upon it (which is what I've been encouraged to do). I have a 45 minute commute and I'm not going to spend 4 hours of my 'day off' driving there and back and attending when they refuse to even give us any details. I'm annoyed with work for various reasons at the moment, so I guess I'm looking for outside opinions, is what they're doing fair and can they insist upon me coming in? My line manager has already called it 'disappointing' when I explained my reasons for not wanting to go.
