Electricians at the Royal Opera House and Jubilee Line Extension are crying foul after a national vote to accept a pay deal they opposed.

Electricians voted 3324 to 2636 in favour of the deal, which gives them a 26% pay increase over two years but reduces travelling allowances.

A number of electricians, including a steward at the Royal Opera House, said they had not received ballot papers, despite calls to their union, the AEEU. The electricians said that this at least 50 workers on the JLE and 30 at the opera house could not vote.

AEEU national officer Paul Corby said: “There will always be people who won’t like the result. We understand their frustrations. We want to modernise the industry to get an agreement to cover the major contractors.”
