My church has asked me to develop a policy to guide the church in hiring contract labor and other vendors. For example, we contract out our grounds maintenance. We need a policy for managing the hiring process if we need to change contractors. We also may need other contract labor services from time to time when volunteer labor is impractical or inappropriate. I know we will want any successful bidder to provide certain information, but I want to be as thorough as possible. Here's the info that I'm wanting from contract labor sources: 1. Completed Form W-9 2. Copy of Certificate of Liability Insurance 3. Copy of Certificate of Workmans Compensation Insurance 4. Copy of State Contractor Certification or License (as appropriate) What else should we request from potential vendors/contract laborers?
