A contractor attended a project meeting that was exclusively for company employees.

The rules of engagement are the guidelines and expectations that define the relationship between the contractor and the company. They may include topics such as communication, confidentiality, access, security, performance, and compliance. The project manager should reinforce the rules of engagement with the contractor to ensure that they understand and respect the boundaries and protocols of the company. This will help to avoid any potential conflicts, misunderstandings, or breaches of contract.
