Sorry to note your helpless situation.
Pl.let me know some more details about your employer defaulting your payment.
Is it a Corporate Co or a small time developers. They have some other projects in other places as well?
How many people were/are working there. Is it still running or closed down?
What's your status, designation- are you a workman or a supervisor?
You worked with them (10 months) which means you were still on probation?
Do you have documents of your employment, appointment order, relieving/experience certificate, pay slips/bank statements etc.?
How many months' salary pending, is't pending like this for many of you or one or two like you?
Appreciate your concern for your beleagured colleagues.
I tend to presume you would have signed some docs, including your appointment order containing terms & conditions, though it's not issued to you.
How about EPF A/cs & contributions to this a/c. (this cannot be ignored as your manpower stated to be at 54 which involve PF compliance.). If yes, it should help you.
Non-payment of salary is an offence on the part of employer.
In the circumstances, to start with, send a regd.notice to the responsible officer, your HR Manager asking to settle your arrears within 15 days. You may take a decision reg.taking up the matter further if they don't settle within 15 days. Yours is not a fit case to take it up legally in view of legal expenses involved. May be if you have organised a union and obtain due recognition to it that helps to safe guard service related issues of your colleagues. Put it every development in writing, building up records concerning service matters.
Let us be positive and work towards achieving the desired.
Do you have tat letter copy you had given to your manager, I mean acceptance letter of your resignation.
What you had written over that letter, can you summarize and about your FnF what you had mentioned?
After this, I can give you the right direction to get your balance payment/salary/FnF.
Thanks & Rgds
