Three weeks after the Air India management introduced revised pay structure for its pilots and cabin crew, two pilots’ unions have written to the airline’s management alleging that the revised terms are in violation of Tata Code of Conduct (TCOC). The unions—Indian Commercial Pilots Association (ICPA) and Indian Pilots Guild (IPG)—have also pointed out other TCOC violations by the company’s HR department in a joint letter issued by them to Air India’s chief ethics councellor on Monday.
