The Hygiene Guard monitors bathroom behavior. Just about anything, if truth be told. Employers can monitor telephone calls with clients or customers to be sure that quality is being maintained. Conversations with co-workers are also subject to monitoring. Under federal law, employers are not supposed to listen in on personal calls, unless the company has told employees not to make personal calls from business phones.
Employers can also monitor their employees' computer terminals.
They can monitor the number of keystrokes entered into the computer each hour. They can track idle time on the terminal. Email and voice mail, likewise, are usually fair game for employers to view. The employer owns the messaging systems and is thus allowed to use them freely. Messages stay in systems even after employees have deleted them from their computers or telephones, often as part of the daily magnetic tape backup of the computer system.
