I am a retired bank employee. Since amalgamation of two banks in the yr.2006, the new entity bank used to pay Ad hoc monthly salary to the employees of the merged bank. In the yr 2012, the bank unilateraly removed discrimination and regularised pay scales of merged bank employees, paid arrears w.e.f. april 2008. My query is, whether the retired employees who were in the employment of the bank in the yr.2008, regularly retired thereafter in say 2009,2010 ...are legally entitled / have legal right to claim the financial benefits from the yr.2008 from the bank. Pl advise.
