I shouldn’t have to say this, but the employee is required to be respectful. If you are having a bad day, don’t take it out on the tenants or other employees. You would be required to answer the phone in a certain way. This is as well designed to be respectful of the caller. If you don’t get along with a coworker, then just deal with them on a professional level. I would expect my employees to be adult enough to act properly. If not, this could lead to employment termination. This will also mean that you would lose all of your support resources that you would otherwise receive.
