The Uttarakhand government on Sunday imposed ESMA to ban the leave of the employees of Uttarakhand Power Corporation, Uttarakhand Jal Vidyut Nigam Limited, and Power Transmission Corporation of Uttarakhand Ltd (PTCUL). The decision has come just three days ahead when the state's power sector employees have planned to orchestrate a protest on October 6 demanding pay parity, revision of allowances, and regularisation of contractual employees.
