I am applying for DTV as remote worker though the embassy in Sweden and got asked for an additional document : "Employment Certificate". I already uploaded my Employment Contract and asked the embassy by e-mail what the difference between these documents were and got this fantastic response:

"They are not the same document. Please contact your company for more information."

The HR person in my company also got no clue as to what exactly is an Employment Certificate. We are about 20 people so not the world's biggest company, but still...

Can anyone here point me in a direction of what document it is exactly that I need the company to produce ?

NB: I already got the Remote Work Permission signed
