FLINT, MI—Hundreds of jobs are available at General Motors’ assembly plant here.

The plant has 400 immediate openings for temporary part-time production workers and 50 openings for permanent subsystems workers, who would be employed directly by General Motors Subsystems.

The temporary positions start at $16.67 per hour, while the subsystems jobs start at $15 an hour. Workers in either position should be at least 18 years old and prepared to work any shift on any day, including weekends.

Part-time workers are limited to 32 hours per week and become eligible for health insurance after 90 days. They would get preference for any permanent full-time positions that become available at the plant.

GM is planning a job fair at Factory One in Flint June 16-17.

GM announced Thursday that production of heavy duty Chevrolet Silverado and GMC Sierra pickup trucks will increase by 1,000 per month beginning in July.
