I am a general contractor that utilizes subs for most of the different trades we perform. I have recently been audited by the state and found out that my NJ subs , who have WC in NJ , are not covered in PA . Trying to see if there is a way that I can continue to utilize this sub and not have problems... I do not perform work in NJ , where they are located . They do quite a bit of work in PA for me and I want to ensure that my business is covered if I continue to use them... Suggestions?
