Is it legally allowed to have 2 persons performing the same leadership role where one was originally appointed to this role and the other is in the 'acting' role at the same time? The one originally appointed is on reduced working hours. Would it not be more appropriate that the second person is appointed in the deputy instead of acting role? Can the first person choose what they want to do and whatever they don't want to do then falls on the shoulders of the second person? Can the liner manager not agree with this choice? A lot of questions, hopefully someone will be able to shed some light on this. Thank you very much
