No. FLSA cases are not “class actions”. No employee need bring or join an FLSA suit if s/he does not want to. However, similarly situated employees are permitted to join an existing FLSA case, and this is a common procedure. If an employee does not join an existing FLSA suit s/he will not be entitled to recover any money as a result of the suit. And as a practical matter, any downstream consequences which may result from one employee bringing an FLSA action (such as schedule restructuring) will likely apply equally to all similar employees in an organization.
