Dear sister,
Lots ppl are in same boat as like u...
Please check below:
"Reference letters in the required format are necessary, please try your best to get them. If after all efforts you are unable to obtain a work reference letter, then you should provide a solemn declaration / affidavit explaining in detail why are you unable to do so. The officers at the VO are aware of the fact that different employers have different policies towards issuing such adhoc letters and may not cooperate in issuing such a letter. Please do attach all your employment records with the declaration. I was unable to obtain a work reference letter from one of my employers and did the same. However please bear in mind that the final decision rests with the visa officer handling your case."
Accumulated Suggestion :
"1) Please descibe the reference letter with your NOC on a white A4 paper and get it acknowledged by your supervisor.
2) Take a copy of photo I'd (company tag photo id) of your supervisor of your company...get it signed by him on it and do attestation
3) Get a service letter from your employee stating you have worked from so and so time with your designation
4) provide an affidavit supporting why you are not able to provide the reference letter in company letter head and attach the service letter provided along with this
5) Submit appointment letter (if exists)
6) Submit Payslip (if exists)
7) Business card of applicant (if exists)
Let me know if u require Sample affidavit for the alternate work reference/job description letter...
Good luck...
