Don’t feel you must be sneaky when checking e-mail or computer files. Clearly inform employees that you intend to pry. Failing to alert them that you may be reading their e-mail leaves your company exposed to claims of violating an employee’s common-law right to privacy. Currently, 27 percent of firms review employee e-mail, but 16 percent say they don’t let their employees know it, according to an American Management Association survey. Have a written policy stating that all electronic and phone equipment belongs to the company, should only be used for company purposes, is not “private” and is subject to monitoring for compliance with company policy.
