The railway unions which launched a trade union action last week have called off their strike following discussions with the ministerial sub committee appointed to look into the issue. 

The sub committee included ministers Sarath Amunugama, Rajitha Senaratne, Ranjith Maddumabandara and Akila Viraj Kariyawasam. 

The sub committee had informed the trade unions that they agree with their grievances, in principle, but need time to look into the matter. 

The railway unions had said they were willing to return to  work if the ministry withdrew the vacation of post letters.
