The union handed out flyers accusing the agency, in a very public way, of choosing efficiency over the lives of its riders.
The union wants its subway operators to slow trains as they enter stations following two recent incidents where New York City riders were pushed in front of oncoming trains.
The flyer reads "Slow down? Over Your Dead Body!" and also claims "The MTA doesn't care if you die."
Last week, union officials urged operators to "enter every station as if there is a pair of yellow lanterns at the entrance," decreasing speed to a maximum of 10 miles per hour.
The MTA took issue with the directive, saying any effort to comply with a speed change "may be considered a job action." It told the union to "cease posting these unauthorized notices."
MTA officials said reduced speeds would effect on-time performance and result in fewer train trips, and that there was no indication that the two high-profile track deaths were caused by excess speed.
