Ineos set a deadline of 6pm for its employees to sign up to changes to pay, pensions and terms and conditions.
The company said yesterday that hundreds of workers had accepted the proposals, but Unite maintained that as the deadline passed, two out of three of its members had said no.
Meanwhile energy giant RWE npower hiked electricity and gas prices by 9.3 per cent and 11.1 per cent respectively from December 1.
The 10 per cent average bill increase will affect about 3.1 million customers, the group said, and follows recent price hikes by British Gas and SSE.
