TWU President Tony Utano said losing two members in one day was “a terrible and incredibly sad loss.”

The union is now calling on the MTA to provide masks to frontline transit workers.

“The MTA must NOW provide masks to frontline transit workers. Otherwise, the moment is rapidly approaching where bus and subway workers will do what is necessary to protect themselves and their families,” said Utano. “Dedication and duty does not mean using transit workers as cannon fodder.”
