The person that wishes to hire you but wants you to work on a trial basis for two (2) months at sixty (6) hours a week without pay can have you agree to such in writing and it would be legal under the law. However, for you to agree to such a long trial period would not be prudent in my opinion.Typically most employers place a new employee on a ninety (90) day trial basis to determine if the employemeny situation will be a good fit for both the employee and the employer.If you do the work "on a gratis" basis, you can demand to get paid but most likely you will not receive any payment. I suggest that you seriously consider not working so long of a period for "free". I prefer the probationary period stated above.
