Final answer:
It is the contractor's responsibility to notify MHIC when a salesperson is hired or leaves the sales team, as part of their licensing requirements.
Step-by-step explanation:
According to most states' regulations, it is the contractor's responsibility to notify the Maryland Home Improvement Commission (MHIC) when a salesperson joins or leaves their sales team. Home improvement contractors are typically required to keep this governmental body informed as part of their licensing requirements. It is not the responsibility of the salesperson, the homeowner, or the local government to report such changes in employment status to the MHIC.
