The 1,700 highly skilled and well-paid jobs “cannot be replaced,” said Andrew Pearson, Unite’s director on the site.
Ford in Bridgend had been a driving force in Welsh automotive since its inception 40 years ago.
The closing resolution in 2019 was attributed to “changes in the call for visitors and costs”.
The Welsh government said at the time that it was “absolutely furious” with Ford’s resolution and that it “expected more” from the car giant.
Currently, 999 workers continue to operate at the plant and BBC Wales estimates that many are expected to end on Thursday, and the rest after the final closure of the plant on Friday.
Pearson, who has painted in the factory for 14 years, said: “It’s a lifetime painting and, in fact, replaced yours.
“I looked for paintings for them for another 20 years and they took it from me. So it’s complicated for me personally and it’s hard for my family. “
He added that Friday would be “very, very moving and disturbing” for everyone on the floor and for the community.
But Unite’s representative said Ford’s staff lived in 23 districts across Wales, so the effect would be felt far beyond Bridgend as well.
Although Pearson continues to criticize Ford’s resolve to close the plant, he argued that the company has done a lot for staff for more than 15 months.
This included investments for retraining, progression and networking projects.
A functioning organization has been created to help create new jobs and businesses in the region, as well as local staff and community.
“We can’t update high-value jobs,” Pearson said. ” These are very well paid jobs, we will not update them. These jobs are not done too often. “
At 76%, the employment rate in Bridgend is close to the average in Britain and above that of Wales in total (74%).
But it depends heavily on manufacturing, a sector that faces uncertainty due to Covid-19 and Brexit.
The most recent figures show that 15. 5% of painters paint in the sector in Bridgend, 11. 4% in Wales and 8. 1% in Britain.
Aston Martin hired a large number of staff in the Glamorgan Valley, but there was sadness in July when Ineos announced that he was postponing plans to build his new 4×4 in Bridgend.
Training opportunities were also given to the pandemic, according to Unite.
The union said no one can simply blame Ford for the end of production at Ford Bridgfinish.
“I make sure we left with our heads up, ” said Pearson.
“This is a global resolution made through Ford Motor Company and has nothing to do with the functionality or commitment of our plant members over the past few years. “
Tim Williams, executive leader of the Welsh Automotive Forum, said there is hope that Britishvolt electric car battery company is creating many jobs in the Glamorgan Valley.
“We want to make sure companies are anchored here in Wales and stay in Wales,” Williams said.
“The industry has a long term, of course, but it will fall in the next two years. “
