@InsuranceLady,
If you work for an electric contracting company, that company pays you a sum base on a contract between the electric contracting company and the company receiving the benefits of the contract ( i.e . the work performed/or will be performed).
If you don't receive healthcare benefits, could it be because the contracts under which you work/or will work don't specify that healthcare insurance must be provided?
If there are 50 workers in your company, how many of these workers actually do the electrical work? This number could be critical to answering your question.
