Train Drivers union ASLEF announced strikes against LNER and Northern because the union says that they are abrogating existing arrangements.
LNER and Northern March 1, Friday.
Also an overtime ban against both, 29 Feb through 2 March.
The issue with LNER is their using of managers to drive trains for £500 a shift bonus without agreement on the main line allowing branch lines like Skipton, Harrogate and Lincoln to be canceled due to lack of route knowledge and lack of training.
The dispute at Northern is about bullying and other measures against workers.
