MTNL has successfully offered voluntary retirement scheme (VRS) to over 1,900 employees.MTNL had, in the past, made several attempts to introduce VRS, but could not implement it due to resistence from employees' association in the C and D group.With the VRS, MTNL's workforce has come down to over 52,000, and that of group C and D employees to about 42,000."We are happy that we successfully completed the first round of VRS. About 525 employees from group C and D took retirement in Delhi and over 1,400 in Mumbai," MTNL CMD R S P Sinha said.
