What HR Policies Are Essential for Project-Based Companies with Outsourced Teams?

Hi friends/Seniors,

Can anyone please guide me on what HR policies will be specific to a project-based company that has its employees outsourced/deputed to a site? Currently, I have an exhaustive list of HR policies, but I would like to frame HR policies specific to the project-based company.

Thanks and regards,
Sajith

Dear Sir,

Thank you for your input. I have already reviewed most of the emails regarding HR policies. However, I am specifically looking for policies that are unique to companies with employees stationed at client sites, such as Sodexo Pass, CBRE, JLL, DLF, etc.

Thanks and regards,
Sajith
