Difference between labour commissioner and labour courts

Both the positions are different and governed by differnt laws i.e., Employees Compensation Act, 1923 and Industrial Disputes Act.

What is the appointment of aggrieved employee and which organisation ?

Is it a query or examination hall question paper ?

The proper way is to get unions/leaders involved, getting all certified copies that show such violations, and if all efforts fail, contacting a local advocate who is in expert in labor matters for further remedy.   Any union leader belonging to the opposition party of the state may guide you in getting further remedy without laborious litigation.
