Guys, I need help/tips here with reference letters. I have worked in 4 organisations so far, starting from 2013.
Company A - Aug 13 - Mar 15 (Flatly refused to issue reference letter, but have all legit documents)
Company B - Mar 15 - Apr 16 (Company shut down, but I have all legit documents like, offer letter, increment letter, salary slips, exp letter, etc)
Company C - May 16 - Aug 17 (Requested ref letter, hopefully will get)
Company D - Aug 17 - Present (Issuing ref letter in next week)
What should I do if the company I was working for shut down and there is no way to get ref letter?
Is there an alternative for reference letter? like notarised declaration or something?
Are following documents sufficient if ref letter not issues?
offer letter, increment letter, salary slips, bank statement, exp letter
Please help me with this. I have collected all other docs except reference letter.
