I understand the reason for you remaining anonymous. There lies the answer for your questions. Laws come to the rescue of all though workers being considered weaker party are protected by some specific labor laws. But the general law of the country is good enough to protect all. The problem lies in lengthy process with huge cost of time and energy and money to the affected individual.
The image of the individual also gets tarnished in the present day highly networked world making his hunting a job all the more difficult if he fights legally. HR today needs to take initiative to give feedback and advice within the permitted level without hesitation. if too many people leave a company, the company also loses image. May be one or two harsh individuals are responsible and they have to be exposed.
Since sacrifice as a tool is no more practiced both by individuals and unions fighting autocratic masters is getting difficult. Yet the social media and others can be used to tarnish the image of the company that practices anarchy. It is quite easy do without mentioning name of the company but by indicating it. What is to be remembered is, the job is very difficult but not impossible. Let the right minded make the beginning.
For any termination on grounds of misconducts, charges has to given to the employee, giving them opportunity to give reply, hold domestic enquiry and then the management can take action.
For the employees who are in managerial cadre (not by mere designation) they have unfortunately less protection under the law.
I can only advice legally upto this point...
