Employer Best Practices For Monitoring Remote Devices

It is generally known that individuals have reduced privacy rights for work-related activity than they have in their personal lives, and that these reduced privacy rights extend to devices owned or provided by their company.

As just one example, consider the federal Electronic Communications Privacy Act, or ECPA, which permits employers to: 

(1) monitor employees' oral and electronic communications to the extent that they relate to a legitimate business purpose;
(2) monitor any communications for which the employee has provided consent; and
(3) access emails that are stored by the employer.

All of these exceptions decrease an individual's privacy rights and reasonable expectation of privacy in work-related matters. However, is "exceptions" the correct word? Exceptions to what? Does this reference a specific privacy law or privacy rights in general? 

(The short version.) Ultimately then, the best practice for employees is to keep work and personal devices and communications entirely separate even in COVID-19 times. more
