You first have to peruse your employment offer letter and verify the conditions and terms that you have been entered into an agreed upon by both, yourself and the management.

If there is a violation in the rules of the emloyment or there is an undue demand and heavy pressure from the management for the performance, make a representation to the management and exhaust the remedies available within the organisation before knocking the doors of law/court

If you are not able to continue with this employment and the you do not like to work here anymore, you may put down your papers anytime without worrying about the other issues in this regard.

You can approach the labor court only if there is any violation in the employment conditions or rules.

This is something that cannot be addressed through judicial intervention. Once you take up a job offer and execute the contract of employment you agree to work within the resources and capacity of the institution. So if the workload has adversely affected your health then you may either resign in accordance with the contract or write to the management to increase the manpower to deal with the workload. No court will issue any directions to the airline.

There is nothing the law can do when there is no violation of right.

There are options before you to either accept the terms of the new or amended rule regarding the nature and time of work.

You can always put in your papers on the same grounds and can get a relieving letter along with your entire dues from the company.

The company cannot forcibly hold you back in the company for any reason that you dont like or not mentioned in the employment offer letter.

You can always choose better employment elsewhere with more perks and conveniences instead of making such unpleasant comments, like "Its is kind of disheartening to realize that law does not cover the rights of even educated working class."

You have not followed the law properly in this regard, instead you put blames on law than to realise your ineffectiveness in this regard.
