The Municipal Corporation of Delhi (MCD) workers staged a protest in front of Chief Minister Arvind Kejriwal’s residence here on Wednesday over non-payment of salaries. Over 1.5 lakh employees of the three MCDs have decided to go on three-day strike from today. They have decided to go on an indefinite strike if their demands are not fulfilled. The cash-strapped North and East Delhi civic bodies have been unable to pay salaries to the workers for three to four months now.
