Personally? This is an example of a Union asking too much. Some of the items being demanded from BART management are that the workers continue to pay 0% of their own salaries toward medical plans and pensions, while receiving a 5% COLA increase in salaries over a 2 year period.
BART already ranks as one of the highest-paid transit systems in the United States.
Sorry, but even though I am a Union worker myself, this is asking too much. I say terminate the negotiations at this point, fire all employees taking to the picket lines, and offer a one-time invitation to those current employees who would like to still have a job to come back at the terms offered in BART's "best and final offer." Which, per NPR, is a 3% COLA increase in salaries over a 3 year period and a 10% contribution toward health care and pensions.
