The nationwide railway strike led by George Fernandes was related to:

Bonus and service condition

The correct answer is option (1) - Bonus and service condition

The National Coordination Committee for Railwaymen’s Struggle led by George Fernandes gave a call for a nationwide strike by all employees of the Railways to press their demands related to bonuses and service conditions. The government was opposed to these demands. So, the employees of India’s largest public sector undertaking went on a strike in May 1974. The strike by the Railway employees added to the atmosphere of labour unrest. It also raised issues like the rights of the workers and whether employees of essential services should adopt measures like strikes.
