Obamacare imposes a 40 percent tax on health benefits deemed too generous by the government. Health benefits exceeding $10,200 a year in value for individuals or $27,500 for families are defined as “Cadillac” plans and are subject to the tax. Health benefits for longshoremen exceed $40,000 per employee, meaning the union would be served an enormous tax bill when the penalty is imposed in 2018.
