Apple keeps resetting my Apple ID password?
It might be the case that someone is trying to gain access to your and your coworkers accounts by trying out random passwords. After a certain number of failed attempts, your account will be disabled to prevent bad guys from continuously trying out passwords.

My suggestion would be to try to find out why it is being reset by contacting Apple support. They can probably tell you the specific reasons for disabling the account as it will probably be logged by them.

Sorry to redirect you, but this is not something we can 'solve' without knowing the reason behind the resets :-)
