More railway workers are to vote on strikes, threatening fresh disruption in the industry throughout the summer, it was announced on Thursday.
The Transport Salaried Staffs Association (TSSA) served notice to ballot dozens of members at TransPennine Express (TPE) for strike action and action short of a strike in a dispute over pay, conditions and job security.
The union is demanding a guarantee of no compulsory redundancies for 2022, no unagreed changes to terms and conditions, and a pay increase which reflects the rising cost of living.
The ballot opens on 29 June and closes in mid-July, so the earliest that industrial action could be taken is 27 July.
The TSSA is also balloting its members in Network Rail, CrossCountry, East Midlands Railway, West Midlands Trains, Avanti West Coast, Northern, LNER, C2C and Great Western Railway (GWR) in an escalating dispute across the railway.
