I am a private contractor with a company out of Michigan. They hire me to teach people how to train on the simulators that they sell. This past year they have been following a trend of paying us outside of the 30 day mark. In a most recent case, I was paid some 60 plus days later. I am under contract with the company that they have 30 days to make payment. My questions are this... 1) Does the law of sighted here apply to me? 2) If so, does the 30 day clock start ticking after the contracted 30 days? 3) Can I charge the company the percentage 1% plus the 5% on my own, or does that have to be filed with a court?
