In its National Compensation Survey on Employee Benefits in Private Industry in the US as of March 2005, the BLS found that the percent of union and non-union employees required to contribute to their medical care plans was 57% vs. 79% for single coverage and 65% vs. 92% for family coverage, according to a report on the survey.
This translated to a monthly cost of $55.71 per month for single coverage for union members and $70.80 per month for single coverage for non-union members. An even greater gap exists for monthly costs of family coverage for union and non-union members, $198.19 for union workers and $292.98 for non-union workers.
The report noted that, for employees participating in medical plans that require employee contribution for part of premiums, employers pay 90% of the premiums for single coverage for union workers and 81% of the premiums for single coverage for non-union workers. For family coverage, employers pay 84% of premiums for union employees and only 68% of premiums for non-union members.
