There may be some companies where exploitation of employees will be happening. To monitor such companies is the duty of the Labour department. But unfortunately, the officers working there will become gloves in hands of the management and keep silent if these managements take care of them.
Another interesting thing in this matter is that there are some people who if given a choice will not work and do politics in the office and take advantage of the weakness of the management. That is the main reason why Government and PSU organisations are to be privatised to bring discipline and efficiency in the system.
Knowledge is power.
