London Underground Workers are set to strike again in August in a dispute over jobs and pensions.

Members of the Rail, Maritime and Transport Union (RMT) will walk out on Friday 19 August, between two already announced RMT strike dates on 18 and 20 August, which will involve Network Rail and 14 train operators, alongside members of the Transport Salaried Staffs Association.

The RMT said the new Tube strike has been prompted by Transport for London’s (TfL) “refusal” to share details of a draft government proposal they received regarding funding of the transport system in the capital, The Telegraph reported.

The union said it is giving TfL until 2 August to give assurances on jobs, pensions and working conditions or the strike will go ahead, RMT general secretary Mick Lynch said.

Hospitality operators, particularly those located in central London and the late-night sector were significantly impacted by strikes held last month.

Sales in the late-night industry over the strike days in June were down up to 40%, according to the Night Time Industries Association (NTIA).
