What to Do When Your Team Quits

The major loss of a team member leaving is the institutional knowledge. They wrote some things that need maintenance and the knowledge on how to do that leaves with them. If I'm an experienced person treading water in a new code base, I may as well get a salary bump by leaving for a new company. Management really doesn't put themselves in our shoes.
If your team quits then you've failed as a manager. Treat it as a learning moment but maybe don't put good effort after bad.
While it's certainly possible the manager is poor, this isn't necessarily true. I'm 43, and have overseen about 10 teams of various sizes in my career - generally 1-3 years each. Sometimes you have good teams, some times you have rockstar teams, and other times you have duds.
It's the luck of the draw, and as a manager, sometimes you can hold a lackluster team together with bubble gum and shoe string, but in the end I've found it's far better for everyone to identify and force out the bad if they don't go of their own volition if at all possible (I've been in contractual/political situations where it was not possible - and that happens, and it is painful).
When a majority of your team quits, if you can honestly say it wasn't you (perhaps based on prior counter examples), then thank them for making your job easier.
It would worry me if one of my managers thinks that since they have led many teams, some successfully, that any negative outcome must mean that the team was bad.
Such opinions are probably the reason many good people leave.
... Lather, rinse and repeat.
After the second round, change employer yourself.
Seen it a few times.
