does management know about this?
Seems to me management should know why the team all of a sudden develops a chemistry problem. The team should have a psychologist.
Get these spoiled brats into therapy or counseling to resolve their emotional issues. This is a multi-million dollar business and you are paid to produce.
If management does not know what is going on in its own house, they should be fired.
Anyway you put it, someone over there is not doing his/her job.
