Why IDA increase w.e.f. 01st July, 2021 and 01st October, 2021 is not paid till today?

Employees of the Central Public Sector Undertakings (CPSUs) are entitled for payment of IDA increase four times in a year, i.e., from 01^st January, 01^st April, 01^st July and 01^st October. So far, the DPE has been announcing the percentage of IDA increase, within a few days of the above mentioned dates. The same had been promptly paid by the CPSUs also. However, the IDA increase that has become due w.e.f. 01^st July, 2021 (3.3%) and 01^st October, 2021(5.5%), were not announced so far. It is already four months since the IDA increase w.e.f. 01^st July, 2021 has become due. What is the reason for this delay? It is because, the DPE (Department of Public Enterprises), which announces the rates of IDA increase, was earlier under the Ministry of Heavy Industries. But, a few months ago, this DPE has been brought under the control of the Finance Ministry. We all know that Smt. Nirmala Sitharaman ji, is the Finance Minister of the country. Now, employees can understand why the IDA increase is being delayed.
