I won't explain too much because my job is pretty niche and I don't want to get doxxed, but I've been promoted to "manager" recently. It's not the kind of manager you're probably thinking of like you'd see at fast food or retail places, I don't determine anyone's hours or pay or anything like that, but I am in charge of assigning work to the people under me and training new employees. The problem is I have to balance the work I do myself and the work I assign to other people. If I keep too much for myself then my bosses wonder why they keep the others around and they fire the peons and I get stuck with all the work. If I assign too much to the people below me then they wonder why I'm even around and I get put at risk of being fired. Obviously I want to keep my job because I have bills and shit but I also don't want to be the person who sits around all day and bosses the people who actually do the work around. I'm kind of just looking for advice.
Tell your minions whatever upper management is telling you/signalling. If you suspect a re-org, increased expectations, increased performance based firings, etc. are going to happen, hint it to them offline so you can warn them without getting in trouble
Make it seem like everything your team is working on is more difficult than expected. Somebody is behind schedule? There were unforeseen complexities that we recently discovered. Somebody finished on time/early? They worked extremely hard and moved mountains to make it happen
