MBTA workers, who have one of the most generous benefit packages in the country, will be required for the first time to contribute towards their health insurance when they retire, an arbitrator ruled this week.
The change takes effect today, requiring that new retirees in the MBTA's largest union pay 10 percent of their health insurance costs.
Workers who are already retired will continue to get free healthcare for life.
Under the old contract, workers paid only $3 or $4 to fill a prescription and only $5 to visit a doctor. The new contract raises those co-payments to between $5 and $20 for prescriptions and $20 to visit a doctor.
