Go legally after the management of the Bangalore office. Do some justice.
Most decent coworkers struggle to continue. The struggle is because of back stabbing, and a management endorsed level of lying and misguidance.
You hear lies all the time. The management retains all the benefits including stocks for themselves. They fire permanent employees within 6 months after learning his key skills.
The US Office never bothered about the welfare of the Indian Office. Constant reminders failed. The Indian management took the US Office for a ride. The US office depended on the poor decisions of the Indian management. The Indian management ignored employee concerns and was never transparent.
