I have recently been seeking work as a sub-contract archaeologist. One company I contacted says that I am required to have Public Liability Insurance, Professional Indemnity Insurance and Personal Accident and Injury Insurance before they give me any work. If they do, no regular amount of work is guaranteed. I may only get a week or two here and there when they need me. I have not long finished my degree and don't have the money to spend on insurances on a maybe chance of getting some work. As a sub-contractor, are all these insurances necessary under Employment Law? I would not be professionally advising anyone or making any recommendations, this is done by the company who may employ me. I would really only be providing physical labor to the company and they do the rest. I thought I would be covered by this company's insurances as a sub-contractor if I do any work for them. Please any thoughts on this might help me.
