More than 60 engineers who look after domestic gas equipment in London staged a one-day strike on Monday of last week.
The strike is the latest in a series of stoppages in a long running dispute with employer Centrica, owner of British Gas, over London allowances.
Gas engineers working on the same streets in central London are being paid rates that vary by as much as £2,500 a year because only some are deemed to be central London workers by the company’s management.
The workers, members of the GMB union, demonstrated outside Centrica’s head offices wearing Margaret Thatcher masks to mock the company’s human resources director Alf Turner. Asked about his influences, Turner quoted the hated former Conservative prime minister Thatcher, saying, “We have a duty, not a right to manage.”
