Such coverage pays some percentage of your salary for many years from the beginning of a long-term disability. I think that both of those numbers vary widely from plan to plan.

Contractors are subject to the health care plans of the company they work for (or whatever they buy on the individual market, if they are self-employed). Part-time employees (less than 30 hours per week, IIRC, although that's probably state-by-state) also receive different treatment.
