Translink management offered a new pay offer at the eleventh hour – which bus drivers, cleaners and shunters have accepted.
The offer means strikes will not go ahead.
Peter Macklin, GMB Organiser, said:
"This shows the strength that workers have when they stick together to demand a fair deal.
“This is a well deserved pay increase and package that our members fought hard for.
“We thank every member who stood firm and earned this decent pay deal for themselves and their colleagues.”
