DHs usually shift work, they changed the shift so he was working Mon-Fri days though (rota is done month by month) and was told it would stay like that (unofficially I guess). He has paid for evening classes starting next week but the manager has said the shift must change to 3 days, 3 nights, 3 off , end of. She will not budge at all on it, even though the others were happy with the way it was. His contract states just hours per week (minimum) but can they force him to go in? Will he be sacked if he doesn't? I cannot see that it's fair he basically has to leave 24 hours a day free, 7 days a week for all the changes. He really really cannot go in 3 nights a week.
