Workers at the Meggitt Aircraft Braking Systems factory in Coventry struck on Friday of last week and Tuesday of this week against their pay being frozen while their bosses get bonuses.
The Unite union members are furious that three senior managers have got bonuses of more than £1.5 million.
Unite regional officer Alan Lewis said, “Our members are justifiably furious. The scale of the greed is nothing short of scandalous.
“A fair increase of 4 percent for the staff in Coventry would cost the company less than a quarter of the cost of the bonuses given to just three men.”
