The ballot, which was prompted by what the union described an “unacceptable pay offer” for staff which did not match industry benchmarks, was due to end on Wednesday.
A spokesman for Northern said: “We have offered a two-year pay deal, which will see more than 5,000 Northern employees receive a 2.2 per cent increase for the current year, backdated to April 2016. There will be a further increase of 2.4 per cent or January 2017 Retail Price Inflation, whichever is greater, for the year from April 2017.”
A loyalty scheme to reward long-service and pay boosts for specific staff who are at the lower end of the Northern pay scale have also been put in place.
