PHILADELPHIA (CBS) — After the union representing SEPTA employees threatened to take “job action” Thursday, the transit system now says TWU Local 234 will not call for a work stoppage. The announcement comes after the union said SEPTA was not doing enough to protect workers during the coronavirus pandemic.

Amid the threat, Philadelphia Mayor Jim Kenney called union president Willie Brown to ask the union not to call for a work stoppage. The mayor said a potential stoppage would have jeopardized lives as health care workers and essential employees rely on SEPTA to get to work.

“SEPTA’s top priority remains the health and safety of our customers and employees. We will continue working closely with our workforce and union leaders to provide the safest possible environment for essential travel during the COVID-19 crisis,” SEPTA said in a statement.

Transport Workers Union Local 234 claims SEPTA isn’t doing enough to protect its employees.

“I don’t think SEPTA is taking it serious enough, in our opinion,” Brown said. “We have right now over 100 positive tests, we have three deaths — they have one in our Regional Rail — that’s four total.”

“We’d like to see them lower the amount of people allowed on the bus, to 15 on the vehicles,” Brown said.

Among a set of demands listed on the union’s website, members want SEPTA to take employees’ temperatures, test air quality on vehicles and limit the number of riders to 15 onboard SEPTA vehicles.

They also want more transparency surrounding which employees have tested positive for the coronavirus.

After the union agreed not to take action, SEPTA says it will continue operating on a Lifeline Service Schedule.
