OUTSOURCED staff working on London’s Docklands Light Railway began a 48-hour strike against plummeting take-home pay today.

Cleaners, security staff, revenue protection workers and travel safety employees downed tools after rejecting an “insulting” 1.8 per cent wage offer – less than a fifth of the economy’s 40-year high double-digit inflation.

Employer ISS is underpaying the workers compared to others on equivalent roles across Transport for London services, RMT stressed.
