It is not "arrears" but you are due to get "allowances." Secondly, you have mentioned the period of employment, but what about the period of allowances? What was the cause of these allowances? Has anything been mentioned in your appointment letter regarding payment of the allowances? When did you claim these allowances? While submitting your claim, did you route these through your Manager? What proof do you have to show that you were eligible for the allowances or that you have submitted these allowances to the HR/Accounts Department?
Has the company given you the Employment-cum-Service Certificate? Have you taken up a job in the new company? I ask these questions because when dealing with your old employer, it should not affect your current employment. Keep your current HR informed about the issues you are facing with the past employer.
Payment of Arrears
When the company underpays an employee, the subsequent monthly payment that includes the unpaid portion of the salary is called arrears. However, the question arises, why were arrears pending for four years? Did you approach HR about the unpaid arrears? If yes, do you have proof? If there was underpayment, you are entitled to your dues. Leaving employment should not be a reason for non-payment. Regarding the clearance of dues declaration, it can be obtained even under duress.
If you believe that the dispute with the old employer will not impact your current employment, you may approach the Labour Officer (LO) in your area and explain your problem. Keep evidence of your past employment like the appointment letter, salary slips, photocopy of the identity card, etc. with you. Let's see to what extent he is willing to intervene. If he is not inclined to intervene, we will decide on the next steps. Inform him that you were compelled to provide a certificate stating that no dues are outstanding against the company.
Thanks,
