Supermarket giant Woolworths faces widespread industrial strife with as many as 2000 workers to potentially go on strike in the coming weeks over pay and job security.

Industrial action at four giant warehouses in Victoria and NSW would likely cause serious problems for Woolworths in supplying its supermarkets and liquor stores.

The workers are pushing for much improved job security, more full-time work, greater redundancy pay-outs and wage increases of $2 an hour, per year. Depending on their wage and experience that could equate to well in excess of 6 per cent a year.

The National Union of Workers last week applied to the Fair Work Commission for the right to take industrial action at three distribution centres in Victoria and another in NSW.
