“There are obvious benefits to getting health insurance at work. For one, employer-sponsored insurance is not taxed, meaning that every dollar of compensation provided as medical coverage stretches further. Individual market plans, meanwhile, are purchased with post-tax dollars. The only way to get in on the tax exemption is to buy coverage at work.
But for low-wage workers, Obamacare  has introduced a new and big drawback to the employer insurance. Namely, anybody who gets access to affordable coverage at work is barred from getting subsidies through the new exchanges. This is even true for people who don’t buy insurance at work; just the act of getting offered employer coverage blocks individuals from using getting financial help.”
