u seem to be confused. If you have hired the person for security duties on company roll then see details given in the offer/appointment letter. If it is an agency then go through the contract signed with the agency. It should have given the break down of each and every details or it would have been a lump sum for each individual's pay. The it is the headache of the agency. Perusal of your problem appears to be with the security agency. Feel free to come back for any clarification.
