CIGNA, United Federation of Teachers Welfare Fund (300K+ workers), Aetna, BCS Insurance, Reliance Standard,

For some reason I think this list will grow to cover nearly the entire private sector.
The current lists exempts around 2,200,000 workers.
There are only 105,229,000 working aged adults in the US, which means just these 700 exemptions account for 2% of the working age population.
If we assume a figure of 76,974,000 employed adults, that number jumps up to around 3% of the working population.
