I have been a self-employed technical writer for over 20 years. One of my regular clients has just decided to require that all contractors(including independent consultants and freelancers with no employees) carry workers compensation insurance(even if they are not legally required to) and also commercial general liability insurance. I do all work for this client in my own home, and no employee of this client ever comes to my home. This client accounts for less than 20% of my work, on average. I have no employees, have never subcontracted any work for any client, and never intend to.(In fact, most of my contracts contain a clause forbidding me to subcontract, because I am hired for my specialized skills.) I easily meet tests for independent contractor(vs. employee) status. I told the client that I would not acquire the insurance(which would end our 10-year relationship), but the client offered to pay for it in order to continue to use my services. The client says that no exceptions to this new requirement can be made for any contractor, regardless of the nature of the work or other circumstances. Most of my other contracts include a "hold harmless" clause, but this apparently will not satisfy this client.
My insurance agent says that no private insurer would be willing to write a workers compensation policy for someone in my situation, but that I might be able to get a policy through the State. My reading of my State's workers compensation statute indicates that even if I had such coverage, it would not protect my client from my filing a "third-party" lawsuit if the client's negligence led to my injury(which is what the client is trying to protect itself against). The insurance agent suggested that I might be able to obtain what he called a "ghost policy"(by which I think he means what is also called an "if any" policy), but that even if this satisfied the client's requirement for a COI, it would not cover me in the event of a work-related accident(it would only cover any employees I might hire, which, of course, I will never do). In fact, it seems to me that acquiring this type of "ghost" policy at my client's expense to cover non-existent risk could even be construed as evidence of an employee relationship. Is my understanding of these cirumstances correct?
Concerning commercial liability insurance, my understanding is that it would cover only any damage I might cause while working on-site at the client's location(which never happens) or any injury to my clients' employees or damage to their property while they are on my premises(which they never are). Given that the risks again are non-existent, would carrying such insurance be of any benefit to either me or my client? And, again, if the client pays for it, could that be construed as evidence of an employer-employee relationship?
