I have asked one of my previous employers to provide me with documentation on my previous employment with them. Since we did not part in good circumstances they refused to give me that document and I would have to go through whole legal process to get it. I had contract psoition with them for 3 years and when working on contract I did not get my pension contributions which I could use to prove the employment. Is there a way for EU institution to check that employment in any way if I give them permissions? I listed that in my resume and I would like for it to be counted torwards my grade.
