As for the new employees, what about the old employees? The old one can't stand it, and there may only be one result. The boss and manager have secrets.
If the old employees have no objection, then there are two possibilities. One is that the above-mentioned store managers are superior, or the salary is not high enough, so let them go. (or leaving has an impact on the family).
But judging from this condition, you should be a newcomer, and you don't like managers like other newcomers. In that case, you just need to consider whether you can learn something. Are you satisfied with your salary? If not, be willful, and you can leave smartly because you are unhappy.
