Unifor Local 444 will welcome new members at TRQSS in a ceremony next week.
Workers at the plant in Tecumseh reached out last year about membership in the city's largest union local. Back in January, 600 new members at the seatbelt manufacturer joined Unifor Local 444.
The union local said it was one of the largest organizing drives since the formation of Unifor.
On Tuesday, the union and TRQSS officials will attend a one-day bargaining handover event at the Holiday Inn Select on Huron Church Road in Windsor.
The union local said since TRQSS workers joined its ranks, other workplaces have contacted it about organizing.
TRQSS opened in 1986 on Patillo Road and is one of the largest companies making seatbelts for the automotive industry.
