The Bakers, Food and Allied Workers Union (BFAWU) held its annual conference this week.
This year the union has been fighting for jobs at the Hovis bakery in Wigan and Warburtons in Bolton.
At Warburtons it succeeded in getting the threat of 121 compulsory redundancies removed.
Some 45 workers took voluntary redundancy or early retirement instead.
And the union got payouts for hundreds of workers at O’Kane Poultry in Ballymena, whose overtime pay was suddenly cut.
BFAWU also won compensation for members injured at work and campaigned for safe maximum working temperatures.
Retiring general secretary Joe Marino congratulated the union for keeping its “independence”.
He then turned his fire on the new Tory government, saying its plans “would make Thatcher quake”.
He told delegates, “We need to reconnect with our people, our class and our ideals. We need socialist ideas in this debate.”
