9 months salary plus incentives pending with previous compny

Did you mention Non Payment of Incentives/salary as reason in resignation?

Yuo should.

If you have mentioned it in letter by ordinary post then attach a copy with email addressed to good offices of appointing authority,MD and raise your demands.

Did you get salary slip,Form16,acknowledgment and acceptance of resignation-handover of charge,NOC,NDC,service certificate/relieivng letter, PF number and a/c slips etc?

Well, I didn't mention non payment of salaries as the reason of my resignation as the new company which I joined had a background verification process as I didn't wanted to spoil relations with my ex employer. it was also promised to me that every month i would be receiving some money until my total outstanding is cleared.

I do have my relieving letter as well as my PF account number which is updated, don't have any salary slips though.

What should be my course of action?

Obtain copy of BGV, salary slips, acknowledgment and acceptace of resignation, FnF statement showing all paybles e.g; earned wages/incentives/bonus/leave encashment/notice pay etc etc,Form16,PF a/c slips of each year etc etc...... .

The FnF wages should be paid o LWD or say within next 3 days or max. by usual pay day.
