Thanks 

I support my colleagues answers 

you can sue or not, depends upon the exact nature of situation and the labour laws of the land where you are working.

Yes, It is right to sue the employer.

It's all depending situtaion & relationship btween each other and local country law. Ideally the employeee should explain and discuss with employer to find out an amicable solution. Both parties are bound each other with professional relationship. Ideally sue is not the final solution..

Yes, you can as per labour laws. Because this consider as a labour right in the law mentioned.

** Depends on the nature of NOC to sue an employer

** If an NOC is required for appropriate government entities, consulate, bank etc; it can be issued by employer

** if an NOC is related to open new company, or any other related activities which can harm the employer business he/she have the rights to refuse for the NOC.

If such term is signed at the time of appointed then company has right to take leagel action for the sack of better future.

I should read and ask for all details during interview and check if the employer provides NOC or not and carefully read and understand the labor law.  I am against going through any legal action towards a company i worked with.  I should bear my choice and agreament.  I should negotiate and propose solutions. 

The law states that employee has the right to receive NOC from his/her employer. In case the employer refuses to give/issue NOC to its employee, the later has the right to file a complaint against his/her employer.

No, you cannot sue your employer for not providing an NOC. The employee is bounded under the labor laws to complete the duration of the contract whereas NOC is not required if the employee has completed two years in service.
