Delegates at the GMB union conference in Plymouth this week were told about the closure of the Fenland Foods factory in Grantham.
The conference called a protest at Marks & Spencer’s annual general meeting on 9 July at the Festival Hall in London demanding the factory is kept open.
Northern Foods is planning to close the factory with a loss of 738 jobs. Marks & Spencer has pulled the plug on further orders from the factory.
Andy Worth, the GMB regional secretary for the East Midlands said, “This is a clear cut case of corporate greed. M&S is making money, Northern Foods is making money.
“The site can make money for these two greedy, corporate giants.”
Delegates were set to protest outside the Marks and Spencer store in Plymouth on Wednedsay of this week.
The conference also debated a special report on the GMB and the environment. Brenda Fraser, from the executive said, “The generation of trade unionists that went before us had to deal with the pollution of the rivers of Britain and clean them up.
“They had to deal with the now forgotten smog in London and bring in rules to clean the air.
“One thing that all these things have in common is that legislation for common action was needed to deal with pollution.”
The conference passed motions calling for the immediate withdrawal of troops from Iraq and Afghanistan, and solidarity with Columbian trade unionists and the Palestinians.
Conference called on the government to restore national standards for fire and rescue services which were abolished in 2005.
A packed fringe meeting saw Simon Walker from the British Venture Capitalist Association debate GMB general secretary Paul Kenny.
