Workers at Toyota’s factories in Burnaston, Derbyshire and Deeside, north Wales will returned to full time shifts from April 1.
Toyota Manufacturing UK has been operating a 10% reduction in hours and pay since April 1, 2009 in reaction to a reduced automotive market.
However, salaries for workers at those factories have been frozen for 2010 following a pay review. Each worker was given an extra five days paid holiday.
Tony Walker, Toyota Manufacturing UK deputy managing director, said: "The next year is key for Toyota Manufacturing UK, employees returning to full-time working and offering a voluntary release programme will allow us to adapt to the reduced market.
"We believe this decision will be welcomed by our employees, who have shown flexibility and commitment to the company during this difficult time."
