So after having been in my job for 20 years (most recently working from home whilst looking after 3 children during lockdown) we get a new admin manager who comes in doesn’t thank anyone for their considerable efforts or make any effort to get to know us or what we do in our roles and instead announces (among other things) that we are no longer allowed to take more than 2 weeks continuous annual leave -first of all can she even do this and secondly if I find that I have to resign as a result of this policy (I can’t afford childcare over the summer holidays) the does this count as constructive dismissal ?
