There could be a long list about the cons but I would mention few important ones:
I would like to start with the unfavourable policies which are made to trouble the employees, for example, If an employee resigns then it is mandatory for him/her to serve the notice period, but, the organization can ask you to leave without giving you any notice period.
Girls should not join this organization until and unless you can handle the inappropriate behavior and actions of the centralized authority.
The Management will ask for your suggestions and will portray as if you are free to do whatever you wish to but that will only happen if the Management also agrees to it otherwise no matter what you say, it will not be heard.
The centralized authority is harsh and partial so adjusting will not be easy
Decisions are taken overnight without consulting anyone and Managers and other employees are forced to follow them causing further restlessness.
