Can my employer monitor my emails and computer activity at work?

What the Law Says

Federal law does not prohibit workplace monitoring outright—but it restricts how and why employers may do it, particularly when it affects employees’ rights to organize or discuss working conditions.

Under the National Labor Relations Act (NLRA), employers are barred from interfering with, restraining, or coercing employees in the exercise of their rights to engage in 'concerted activities for the purpose of collective bargaining or other mutual aid or protection.' This includes discussing wages, hours, safety, or unionizing—even via email or messaging tools.

Monitoring becomes unlawful if it’s used to suppress or retaliate against such protected activity. For example, secretly recording employee discussions about forming a union—or disciplining workers for emailing coworkers about pay concerns—may violate Section 158(a)(1) of the NLRA.

The NLRA applies to most private-sector employers (except airlines, railroads, and government employers). It does not require employers to notify employees of monitoring—but courts and the NLRB have held that overly broad surveillance policies (e.g., banning all non-work email use) can chill protected speech and thus violate the law.
