Some 4,000 aircraft workers in the Amicus union held an unofficial strike on Friday of last week.
The workers at Airbus Broughton in Flintshire, North Wales walked out after growing frustration with management.
Last month the company announced it was axing hundreds of jobs at the plant.
Two-thirds of the 7,000 workers at the plant, which makes wings for Airbus’ A380 passenger jet, were involved in the walk out.
According to Billy Mullin, Airbus worker and Labour councillor, “There was disappointment with the company’s restructuring programme. And they are looking at job losses of around 800 on the site. Added to that the company is looking to outsource parts of the business.
“The final straw was when the company decided that they weren’t going to give workers any profit related bonus.”
After hearing about the bonus, workers demanded a meeting during the morning shift and unhappy with the answers they got, walked out.
