Your original certificates/testamonials are your property and company can not have any lien on it.
There are threads to indicate that employee’s lodged police compalints and even an ASI/Havaldar was sufficient to get back the certificates.
Hope you will take it in positive spirit.
Why employees suffer?
Because the non united employee’s are viewed as ill informed, without any support, loners, and are susceptible to exploitation…………………….by unscrupulous employers.
The employee’s that stay in such expensive cities as paying guests, away from their homes are more susceptible since they have expenses to bear and those working on low salary don’t have reserves.
Employers know that they will count every penny won’t like to spend for legal consultation with a lawyer.
The non united employee’s are unaware of the labor laws and their rights.
Did you consult elders of the family, competent and expereinced well wishers, employee’s unions leaders,trade unions e.g. CITU/INTUC/AITUC/BMS leaders, Labor Law Consultant/Service matters lawyer/law firm, or even your family lawyer before handing over the certificates?
Did the company demand certificates from you in writing?
Did the company issue any acknowledgment/receipt to you for the certificates?
Did you record the calls during which company demanded money against certificates?
Has the company paid you refund of expenses to attend the interview: e.g. to draft/type/submit application,parking fee,travellin expenses etc?
Has the company spent on your interview alone (total expense/toal no. of candidiates) and expense = 5% of annual CTC offerred to you?
It is good that you are not joining such company!
First build sufficient evidence with the help of your counsel and eldrs and then submit a complaint thru your counsel.
You will get your certificates.
