In a representation, the workers, mostly women from Punjab and Gujarat, said, "We would urge you to conduct a public inquiry into the sacking of workers and the employment practices of the company Gate Gourmet, world's largest supplier of in-flight meals internationally."
Despite making huge profits, the company had behaved in a "high-handed manner" with them, the workers said in their representation.
The workers, summarily dismissed two months ago for protesting against proposed redundancies, took their grievances to 10, Downing Street, the Prime Minister's office, on Tuesday after rejecting a compromise offer which, they said, was "heavily loaded in favour of the management."
The petition was handed to the Prime Minister's office after a protest outside Downing Street.
"The management told us in January 2005 that they were planning to make 670 people redundant because they were "surplus" workers and negotiations had been going on over this between our union and the management.
"Despite the management's claims that they had 'surplus' workers, on August 9 this year we were told that 130 private agency workers were to be employed from the next day onwards.
