Leaders of the train drivers’ union Aslef have received a new offer from the Government in a bid resolve its long-running pay dispute.

Industrial action by both Aslef and the Rail, Maritime and Transport (RMT) union over the last two years became the longest ever in the railway industry.

The Transport Salaried Staffs’ Association (TSSA), which represents workers in the transport and travel industries, has also had its members stage walkouts before accepting offers from train companies in February 2023.

Aslef members have staged 18 days of strikes since the dispute started.
