Can we limit the amount of time employees spend on social media sites on work time?

Yes. While the Stored Communications Act (SCA) may prohibit employers from reading the content of an employee’s social media account (even if the employee is on social media during work time), the SCA does not prevent employers from establishing policies about acceptable use of social media on work time. Employers may discipline employees for improper use of work time, and may even monitor the number of visits or the time spent on social media sites by employees. Discipline may be imposed if employees violate such a policy.
