First I’ve heard of it.

lets see:

"The drivers have not had a pay increase for five years and first balloted for strike action in June 2022.

Aslef general secretary Mick Whelan said: “Since then train drivers have voted, again and again, to take action to get a pay rise.

“It is now a year since we sat in a room with the train companies – and a year since we rejected the risible offer they made which they admitted, privately, was designed to be rejected.”

Strikes will take place on Tuesday May 7 and Thursday May 9. An overtime ban runs from May 6-11.

The drivers have held 14 days of strike action since the dispute began.

The government will use taxpayers’ money to compensate operators for lost profits."

Sounds reasonable tbh.
