These are standard client terms and conditions for any “employment business”. The document strongly protects the employment business but fairly treats the client.
An employment business is one that employs workers and hires them to clients, usually on a temporary basis.
The workers are employed by the employment business and not by the client.
You can use these terms as an agreement under hand, or you could easily adapt them for your website.
Your business might specialise in providing staff for a particular industry or role, or be a generalist provider of temporary workers.
The document includes provisions and options related to:
indemnity and limitation of your liability for the work your employees perform
payment of fees
recording of work completion
