My friends worked in a company for 1 year. They are best performers and rewarded by company. Due to issues with vice president and CEO, they are asked to leave the company. They got relieving and experience letter from company. They got a letter also from Account manager that they will pay 3 months salary as per appointment letter.But till now they did not pay. They are prolonging from December. It was mentioned very clearly that they will clear within 1 months from last day of work.Whenever they send an email to HR and Finance Manger they will reply that we will clear so and so date but they did not stand. They postponed more than 10 dates. They are asking me how can they take action on company as I am working as HR.Please suggest what are the ways to get their money as it is more than 6 months.
