Workers at Jaguar Land Rover, including employees at two plants in the West Midlands, have voted overwhelmingly to accept a deal including a two-year pay rise which union leaders said would secure their jobs for a decade.
Unite said 74% of workers at Castle Bromwich and Solihull, along with Merseyside plant Halewood, accepted the deal which will see pay increase by 5% this year and by RPI inflation plus 0.5% the following year.
The deal cements the future for around 16,000 workers across the company for at least another decade, according to Unite.
Union official Des Quinn said: "The workforce is over the moon. They can now look forward to the future in the knowledge that their jobs and livelihoods are secure for years to come.
"In these worrying times for workers and their families it is great to have some good news but it is no more than these workers deserve.
"It also shows what can be achieved when a manufacturer works with the union and backs Britain. These are the sort of jobs - highly skilled and secure - which are essential if our country is to grow its way back to economic prosperity.
"Unite and the workers are keen now to continue our work with the company to build upon JLR's proud reputation for making some of the best vehicles in the world."
Unite said it was hopeful that the new deal would lead to the creation of thousands of jobs at the three sites.
