Employees of state-owned airline Indian, who were on a protest for the last few days over demands including wage hike, threatened on Friday to strike work.
Though no final decision on the strike was announced, the Air Corporation Employees' Union (ACEU) said the delay by the Indian management in implementing the 1997 Demand Charter could lead to employees staying away from work, an ACEU statement said.
It said the responsibility for strike action would "totally lie with the management which was not showing any interest for settlement of the genuine demands," ACEU Regional Secretary SD Bhatt said.
The employees, who have been wearing black-badges and observing hunger strike for the past few days, staged a lunch-hour demonstration on Friday at their office near the Delhi airport.
The ACEU would continue sit-ins and hunger strikes near the airport entry gate on December 30 to January 1, the statement said. The ACEU would chalk out its future course of action after January 1.
Their demands include immediate settlement of the Demand Charter of 1997, higher wages, career progression and a pension scheme.
"On wage revision and career progression, everything has been negotiated and settled, but the management is unnecessarily causing delay," the ACEU had said in a circular to its regional affiliates recently.
