Hey pal, thanks for the help. Both my LOE letters are clearly dated, I checked last night, see below, so I'm not really sure what they mean there. Unless they mean the letter of explanation, although I just checked and that is also dated.
My foreign work experience as shown in the letter is from 15th of April 2012 until the 25th of April 2014. My Canadian is October 2015 - April 2016 as a bartender (unskilled) but was then promoted to manager (skilled) and worked until the end of September 2017. Here is my letter...
I presume it's just not good enough, the fact I was underpaid (we were rewarded with extra meals and being able to pick our own hours/schedules) and the fact it was a mixed role, even though my manager explained even when I was on a bartender shift I was still doing the managers jobs.
Seems a bit harsh to be honest
