I’ve been driving for a chartered accountant working in a private company for the past 10 years. He used to pay me a fixed amount every month, but now wants me to leave as he no longer needs a driver. I’m worried because this was my main source of income and it’s tough to find another job. Are there any laws that can help me get something like gratuity, pension, or even a small compensation for my long service? I know he earns a lot more than what he paid me. Any guidance would be greatly appreciated.
