We have agency resources on our work site,

1. What rules and regulations should be informed / given to them when they report to work or is there any document that needs to be given to them along with an acknowledgement receipt.

2. Who is responsible for their Work status check?
3. If there is Disciplinary or Grievance related matter who will investigate it Agency itself or their work place Employer

I will appreciate if any one can help me out or even send me format.
