Do have any rights on a law suit other than workman's com ?

I would recommend you consult with a personal injury lawyer in your state that handles work comp and/or slip and fall cases. If you were on the job, you might be limited to work comp. However, if there was negligence on the part of a third party that created an unnatural accumulation of ice, you could possibly have a case. Laws vary greatly by state for premises liability, so it would be best to consult with a lawyer in your area.
