More than 1,000 union workers at Sunoco refineries in the Philadelphia area will stay on the job for now as contract talks continue.

Union employees at the oil company’s plants in Philadelphia and Marcus Hook were ready to walk out at noon on Sunday. But officials with the United Steelworkers say they’re making progress in talks with the company, and pushed back the deadline.

The union has been fighting to keep staffing at current levels. They say Sunoco wants to cut nearly 200 jobs from the 1,300 working at the two refineries.

The company says those plans are in line with what’s happening at its refineries across the country. They insist those plants continue to operate safely.
