Hello again, Beth. Thank you very much for clarifying the situation.
It does appear that the employer owes you wages
based on the previous agreement, which was just revised last month. Their failure to pay wages when due would normally constitute a violation of state law and provide you with grounds to pursue a wage claim against them.
Here is a link which provides information on filing a wage claim with the state DOL, which has the authority to investigate and possibly collect the wages owed on your behalf at no cost to you.
If you retain an attorney to pursue the claim, attorneys fees are generally not recoverable through a lawsuit, so it is usually best to pursue a wage claim through the state agency first. If you have reason to believe the employer may retaliate against you for pursuing your rights, then it would be preferable to retain an attorney in an effort to retain your employment.
I hope this helps clarify the situation for you. Please remember to rate my service once you have all the information you need. If you have any other questions, please ask me – I’ll be happy to respond. Thank you!
