Yes, certainly you can take legal action against them, but before taking up this matter with a lawyer, I would suggest you meet your local/regional labor commissioner/inspector with your written complaint against your employer and also to your local police. You also have to supply your documents to them with your written complaint, such as your appointment letter along with the issued termination letter by them, your salary slips/bank statement, and your EPF details.
Understanding Termination Reasons
Second, if it is a TERMINATION, there must be a valid reason or something wrong on the employee's end which forced them to take this action. Therefore, I would like to know more about this termination letter and the reasons stated in it by them.
Reviewing Employment Terms
Third, you also need to read your appointment letter and termination clause for more information, which will give you the T&C of your employment, which both your employer and you are bound to follow.
Concerns About Unpaid Dues
Fourth, you said that you got this TERMINATION letter from your employer on the 10th of Jan, 2014, and also have not been provided your salary for December 2013 and other dues. This clearly indicates there is something wrong, which you must discover or share with us if there is anything you have forgotten to include in your query. To terminate any employee, there is a procedure which the employer has to adopt/follow and issue a notice to the employee before issuing a termination letter by stating a valid reason or something which favors the employer’s action and against the employee. (Employment/Appointment Letter T&C’s apply)
Moreover, TERMINATION never implies that an employee who’s going to be terminated for whatever respective reason won't be able to get his/her dues or the pending previous month's salary. A complete settlement (F&F) with the effective date of termination (if there was no notice period or special terms defined for the same) is also a right of the said employee.
What I feel is that you still have to share complete details of your case and why your salary and dues for November-December 2013 were not paid previously.
Retrenchment vs. Termination
The other thing suggested by your query and your pending dues is about the financial crisis of your company, which forced them to take action, which is RETRENCHMENT, but it is certainly not a TERMINATION.
Lastly, in both cases, your applicable employment terms can help you a lot actually.
