I am a sales person for a company in New York who is in the business of sales representation for other clients (ie: companies retain us and use our sales force to sell their products). One such company we "repped" (we will call them Company A) held a sales contest, which I won, and I was told by Company A I was getting a bonus for winning the contest, which they would pay me directly. Right after this happened, my company (we will call them Company B) was purchased by another company (we will call them Company C). Apparently, there is a discrepency over past funds owed by Company B to company A, which Company C is reluctant to pay. As such, company A has told me they are not going to pay my bonus until this is rectified. It has been going on quite some time. I'm not sure what I can do since I am not an employee of company A, but I am still an employee of Company C. Are they allowed to do this? Is there anything I can do? Can I file a claim with the labor board even though I am not an employee of Company A?

No, this is not a matter for the DOL.

Whether you are legally owed the bonus is something an attorney in your state who can review all the relevant documentation will have to tell you.
