They are also opposed to implementation of recommendations of two parliamentary committees which include separate domestic and international airlines under a single holding company.
"We will launch an agitation and gradually build it up by holding demonstrations and other forms of peaceful protests. A decision on having a strike will be taken by all the 11 unions, including those of pilots and cabin crew," V J Deka, spokesperson of a joint platform of the unions, told PTI here.
He said the unions platform, Civil Aviation Joint Action Forum (CAJAF), would meet next week to decide whether or not to go on a strike.
Besides protesting the delay in payment of salaries and "long overdue" wage revision, CAJAF is demanding that several recommendations made by Parliament's Committee on Public Undertakings and Standing Committee on Transport, Tourism and Culture on Air India, be implemented.
Deka said the CAJAF was also protesting the "lack of facilities" for staff members in the newly-built Terminal-3 of the Delhi airport, which would be opened on July 3.
The facilities, which exist for the staff at the present location of Air India at Terminal 1-B, include canteen, parking facilities.
"These facilities are not being provided to the staff in the proposed new terminal. If the management or the airport operator doesn't decide on these minimal things, we will be constrained to decide not to shift to the new terminal," Deka said.
