Winding-up Petition for Unpaid Salaries and Full and Final Settlement

Our full and final settlement has not yet been made by the company. It's the habitual practice of that company. whoever demands strongly for the full and final settlement, they will threaten by sending legal notices. Further, the company will not support and fails the employee verification process for such employee. Last time few employees have been tried to file a police complaint for the delay in salary for the period of almost 3 months. Then they've been terminated immediately and notices were sent to them as the company name and fame have been spoiled and demanded to pay 25 Lakhs to the company as compensation. It's been more than a year. All employees are feared of getting involved in unnecessary disputes with the company. We all held non-managerial positions. 1.
