PHILADELPHIA (WPVI) — septic officials spent Friday in a conference room at the Wyndham Hotel in Old City as they negotiated with the union representing the workers who authorized the strike.

Talks have been going on there for more than a week, but this is not the only possible strike situation facing the city. The three unions representing some of the city’s most essential workers are considering the same action: a strike.

“Both sides are at the table, we’re having productive discussions,” SEPTA spokesman Andrew Busch said of negotiations with Transit Workers Union Local 234, which represents workers who handle transit operations in the city of Philadelphia. This union represents more than 4,000 city SEPTA employees.

“We’re still having trouble coming up with salaries and other costs because of the funding shortfall that SEPTA has right now,” Busch said.

Although the union voted to authorize a strike, it was averted as both sides remained at the bargaining table at the Wyndham Hotel in Old City. Also negotiation with SEPTA is Smart Local 1594the union representing suburban SEPTA workers.

They voted to authorize a strike, with the contract expiring at the end of November 18

“We met with them the other day and the talks didn’t go very far,” said Anthony Petty, general president of Smart Local 1594.

Demanding better wages and a safety plan, SEPTA workers in the suburbs have the same demands as SEPTA workers in the city.

“We feel for them and they feel for us and we stand with them,” Petty said.

Another group that voted to authorize a strike is blue-collar workers in the city of Philadelphia, including sanitation workers.

“(Our) contract expiration was July 1, 2024,” said Greg Boulware, president District Council 33.

District Council 33 is the largest labor union in Philadelphia. They are negotiating for better wages.

“Our members, on average, make between $39,000 and $45,000,” Boulware said. “In a city like this, it’s not a living wage.”

As the city of Philadelphia negotiates with only one union, SEPTA also remains in negotiations — all hoping to avert three strikes.

The union representing suburban SEPTA workers breaks off negotiations over the weekend. They will return to the table on Monday. If they don’t reach an agreement, service will be affected starting Tuesday,

However, even if both city and suburban SEPTA workers go on strike, Regional Rail service would not be affected because those workers already have a contract.
