The best answer I can give you is that your question is really state specific. In other words, what CA requires of the private employers may not be the same as what PA requires. So please look up a PA labor lawyer from this web site and contact them. Generally the people asking these questions are the employer, so you may want to ask the attorney if he represents the employee (plaintiff) or the employer (defendant). Since I have generally represented only the plaintiff employees, I do not know this answer. Sorry.
