In the back of your mind, you probably suspect e-mails sent from your work computer are monitored. But unlike the distant, impersonal "Big Brother" you might imagine, your every word could be read by any one of a dozen IT employees housed right next door. Most companies, particularly their IT departments, now employ software to flag suspicious patterns and keywords. (Be careful how you use the word "secret"!) But the truth is any e-mail you send could be read for any reason.
Not only that, but a flagged e-mail could lead to a full-on forensic data investigation. This means that every Web site you've visited, and every document, program and setting on your hard drive (even if you think you've deleted it) could be under investigation. The same goes for calls, texts and e-mails from your employee-provided smartphone. One employer even used the GPS it had installed on an employee's work phone to gather data that he was leaving early (while still on the clock), and used the information as ammunition to fire him [source: Derene].
