Union workers at Honeywell Aerospace in South Bend aren’t working Monday morning, May 9, after the company and UAW Local 9 couldn’t come to an agreement for workers’ contracts.

The union and the company were negotiating a new contract for more than 300 workers for about three weeks, our news partners at ABC 57 reported.

The previous contract expired May 3, but union members continued to work until Honeywell decided to lock out union workers at 6 a.m. Monday, FOX 28 reported.

“This morning at 6 a.m. they decided to lock us out until we reach an agreement. So at 6 a.m. they started going through the plant and escorting (every union member) out,” UAW Local 9 President Adam Stevenson told ABC 57.

Union workers are seeking pay increases throughout the term of the contract and a different healthcare package.

“The biggest point was healthcare,” Stevenson told ABC 57. “The healthcare they were looking at was going to be open ended so they could change it year after year without notifying us.”

Honeywell officials told ABC 57 they’re confident that the company and the union will reach an agreement that provides such increases as well as comprehensive benefits.

Salaried employees and trained temporary workers are operating the South Bend location of Honeywell until a contract is finalized.

Though the union members were not working on Monday, dozens gathered outside of the building near the corner of Bendix Drive and Westmoor Street.
