Almost 1,000 construction workers at Heathrow’s Terminal 5 have threatened to strike in a row over bonuses.
The builders have demanded an extra £1 per hour to cover additional travelling costs to reach the £4.2bn development.
They have warned that they will stop work for three days next month and have provisionally set the dates for industrial action as 8, 15 and 22 December.
Representatives from the Union of Construction, Allied Trades and Technicians (UCATT), the Transport & General Workers’ Union (T&G) and the general worker’s GMB union plan to ballot workers at Laing O’Rourke, one of the main contractors, on 16 November. About 600 staff from Balfour Beatty and Amec are also expected to follow suit with further ballots.
Union officials claim that bonuses have been frozen for three years.
A spokesperson for Laing O’Rourke said the company was unaware of any potential strike action.
