The best options is:
Email all the right people (manager, hr) that you are reigning effective immediately and as per contract your last date will be so and so. Ask for instructions to return company owned assets, etc.
Meanwhile try to arrange loan so that you can survive until you get pay check from next company.
This is basic. You can try other over this like:
-
ask new company to give a joining advance given your situation, depends on your equation with them.
-
You can also work on contract while serving notice period. This is not legal, but if current company does not know then it’s ok.
Another path is just email your manager that you are moving on as they have not fulfilled their contractual obligation of paying salary. Do you are leaving effective immediately. Add some masala in this email like a history of communication that salary will come and failing to do so, and etc. ask how you can return company assets. That’s it. Don’t even login or use the laptop. Remove company email from phone. Just answer phone calls if you get any. Don’t even respond to email or WhatsApp.
Remember, a company not able to make payroll will not have energy to sue one employee for leaving. They will threaten you, but if you get notice get a local lawyer to give return notice. This should take 10-15k max to start with.
Last option, just don’t work, don’t respond, keep laptop. Join new company or find another one.
Don’t be afraid. Someone is screwing with your life and family. Fight back.
Before you do anything, arrange capital for 3-6months for your family (may be mortgage gold, etc.). Have a peaceful mind and keep interviewing.
All the best.
