Email Monitoring at Work

A new survey finds large companies often monitor e-mails their employees send to outsiders.

The survey by Proofpoint, a messaging security company, finds that 38 percent of companies with at least one-thousand employees have people whose job it is to read their co-workers' email.

It's not that the boss is nosey, though.

A survey of almost 300 decision-makers at big companies shows growing concerns about company secrets going out via email and other electronic communications.

In fact, companies estimate that more than 20 percent of outgoing email contains material that poses a legal, financial or regulatory risk.

And the companies are not putting up with it.

Almost a-third say they've fired an employee for violating email policies.
