Always keep all your documents in order, whether you need them immediately or not.
Let this be a learning experience. From now on, insist on all documents, either in physical or electronic form. Then keep them organized so that you can find them easily when you need them next.
Can I get the relieving letter from a previous employer, two years after resigning?
I recommend that you ask. Most reputed employers store employee records and documents electronically. They can print a document and sign it without much hassle. If your Company X is not one of them, you will have to chase some people to dig out old records.
They would certainly ask you the reason for delay in collecting the document. Just tell them the truth instead of creative lies.
Will not having a permanent relieving letter affect my employment with other companies in future?
This would cause you some inconvenience, but is unlikely to create any problems.
Many companies now ask for relieving letters from all previous employers. They will ask you why you have only a provisional relieving letter. Some may ask you more questions, or for additional documents.
Will I be able to manage with the provisional relieving letter?
You can "manage" if you are ok with some hassles. I do not expect a company to take extreme actions like withdrawing the offer or firing the employee for having only a provisional relieving letter.
Will Company Z accept my provisional relieving letter?
Each company has its own policies to deal with the situation. Some companies may ignore it (especially for an employment that last only 8 months), others may ask you lots of questions or do additional background checks. Some may ask you to sign a declaration or affidavit. We cannot tell what the specific Company Z would do.
Go get that relieving letter now, whatever it takes.
- The more you delay it, the more awkward it gets to explain the delay, so don't wait until the next time.
- Getting the relieving letter now will save you from all the future what-ifs.
- When you do not have the relieving letter from the immediately previous employer, you can reasonably say, "I have not got it yet". 2 years later, you can no longer say that with a straight face. :-)
