"The Union Cabinet chaired by Prime Minister Narendra Modi today granted ex-post facto approval to the proposal for undertaking cadre review of the Indian Postal Service," an official statement said.
The review will enable the department to meet functional requirements and strengthening the cadre structure both in the headquarters and in the field, it said.
It will also reduce the existing stagnation and improve the career prospects of Indian postal service officers.
However, there will be no change in overall number of posts in the cadre as some positions will be decreased.
"For undertaking the exercise, necessary consultations on the CRC recommendations with Ministry of Finance and the Ministry of Personnel, Public Grievances and Pensions have been duly completed. The Department of Expenditure have conveyed their 'no objection' to the proposal," the statement added.
