Kindly check the transfer clause in your service agreement/appointment letter. At the time of joining, you may have received this document from your employer, and it should be acknowledged by you. This clause is quite common, and under its provisions, management reserves the right to transfer an employee's service from one office to another or to any sister concern. If an employee refuses to accept a transfer, such refusal may be considered misconduct.
Regarding wage issues, after 11 years of service, your nature of work may fall under the skilled category. Please check your state's minimum wage rate as per your schedule of employment/nature of work. If the minimum wage rate is lower than your current wages, you have the legal right to claim your unpaid wages from your employer along with any arrears.
If your current wage rate is equivalent to or higher than the minimum wage rate, you do not have the legal right to challenge your employer.
Thank you.
