Understanding the 10% Remuneration Deduction
From your statement, I am providing you with an answer.
"The reason behind the 10% of remuneration is that the employee has to complete 5 years with the company before it becomes liable to pay as per the rule. However, these words are nowhere mentioned in the offer letter or appointment letter."
When the term "CTC" is used, it includes all the benefits that the employee will receive on a short-term and long-term basis. In your case, they have deducted an amount (10% of CTC) and informed you that this will be given to you after the completion of 5 years. I believe they have included "Gratuity" in your CTC. But if this is indeed "Gratuity," it cannot be considered "individual."
Requesting a Salary Breakup
Returning to your query about the salary breakup, it is your right to request a salary breakup. You mentioned that you have received an appointment letter. I am unable to understand why you accepted it without a breakup and then continued to work for an additional 10 months, which is unacceptable.
Additionally, if they provide you with a payslip, you may find the salary breakup in it. However, please note that in the payslip, only "Gross Salary" is displayed and not "CTC." Just for your information, 'Gross + Employer's contribution of Statutory compliance = CTC' is a common formula in the current payroll process.
Receiving Full and Final Payment
The new HR personnel informed you that "You will receive all your remunerations associated with your profile," which means she implied you would receive what you are supposed to get, not necessarily what you are requesting. You should have received your "Full and final" payment and a "Relieving letter," which will assist you in securing a new job. It is beneficial if you have already received these documents.
Advice for Future Employment
Lastly, as you are in sales and face targets and job uncertainties, but likely receive a high package. My suggestion to you is, instead of spending time on legal proceedings, focus on finding a good job. This time, do not accept any verbal communication; ensure everything is provided in writing.
If you still wish to pursue legal action, you may contact the Local Labor Commissioner's office in Mumbai and file a civil suit with all available documents. The contact details can be found on the internet.
I hope all your doubts have been addressed. Feel free to reach out for any further queries.
