The Calcutta Municipal Corporation (CMC) has issued a notice asking all its employees to attend office from Monday.

The notice issued on Saturday by the municipal commissioner said “all the departments” of CMC “are directed to ensure attendance of the entire staff strength”.

Officials said the civic body’s revenue earning had been severely hit in the two months of the lockdown. More staff would mean the treasury offices could work in full strength and people could pay their taxes in these offices.

The officials also added that with the monsoon approaching, cleaning of rainwater catchpits, last-minute road repairs, checking of drainage pumps and various other work that is part of pre-monsoon preparedness have to be completed at the earliest.

Attendance of all engineers and officials would help meet the objective. “A full strength would mean we are prepared to deal with monsoon exigencies,” an official said.

“Even if some of the pre-monsoon work cannot be done before it starts raining, there should be adequate strength to deal with situations arising during the monsoon.”

Another official said the revenue earning of the CMC had been badly hit. Metro had on May 29 reported property tax collections had dipped by over 85 per cent for April-May, compared with the same period last year.

An official said other revenue sources such as building plan approval, amusement and trade licence renewal have been hit, too. These are key revenue earners for the CMC and a full staff strength is needed to rev up revenue collection, the official said.
