Indian Airlines (IA), India's national carrier, faced numerous human resource problems that contributed to its losses over many years. IA lacked proper manpower planning and underutilized existing staff. Its employee unions frequently resorted to strikes over wage demands, disrupting flights. IA's staff costs increased substantially through the 1990s as wages and bonuses rose, accounting for a large portion of its losses. IA had more employees per aircraft than competitors and struggled to control rising wage costs, despite several attempts to reform productivity incentive programs. Recurrent industrial action and inability to manage staff costs effectively hampered IA's financial viability.
