Under the law, your employer is allowed to use employee monitoring tools to check up on you while you’re on the clock. Generally there are no restrictions on a federal level, but individual states may include their own regulations. For example, more and more states are demanding that the employer notifies the employee that the system monitoring software is in use. In any case, this is more a matter of common decency and professionalism. Even though there’s no legal obligation, the employer should still tell their workers about these ground rules.
