We have a subcontractor who has been working with us for 3 years. He did not sign a contract with us, and bills us for his services (rather than being on payroll). Due to some personality fit issues we are considering ending his services in a few weeks and we want to clarify what our obligations are if we do so. If we terminate his services, we will recruiting to fill the position, but this individual is not who we want to have in the business going forward. Can you please advise what are obligations to this subcontractor are? Thank you.
