Hi, I am hoping to get some advice on managing a number of flexi time arrangements. I am new in post as manager. It has become apparent that a number of employees have already agreed flexi arrangements (small business, no HR department). I am absolutely supportive of flexi arrangements where needed and where it is possible. The problem is that all of these flexi arrangements (and there are a variety of reasons for them) require morning shifts, when the demands of the business are static across a 24 hour period. They are in place for around 25% of the workforce! I have read that once agreed that flexi time forms part of the contract once agreed and cannot be unilaterally changed. However, the current level is not sustainable. I intend to do individual reviews and hopefully agree changes where possible, but if agreement is not forthcoming, I still need a solution! It would not be financially viable to employ more staff to cover the hours due to the agreed shift patterns. There are some arrangements that are likely to need to continue (and I will advocate for those employees), but others have been agreed because they are preferred hours rather than for a particular reason. Could someone in the know give me some pointers please?
