Is It Worth Reading Employee's Email? Especially recommended for R-t managers.
If you're a manager and you want to know what your employees are up to, I suggest reading email as a last resort. Of course, if you're concerned that someone is stealing, or using your company to do something illegal or unethical, reading email may be your only trail. But if you want to check on what an employee thinks or how their work is proceeding, talk to the employee.
