I worked for them for three days, in their casual category, six years ago. I was obviously too literate for the comfort of the minority bosses that I had, and was told an obvious lie, to the effect of: "I was going to hire you, but I heard you were saying things about me, behind my back. 'X' [The functionary between he and I] told me that."
Well, 'X' (I'm omitting names) was never produced to explain this, and that was that, so I told him to take me off their list. The only thing I can think that was the cause, was on the second day, when I calmly asked 'X' why it was she felt she had too speak to me as I were a child. Well (as was her default tactic), she immediately started crying, whereupon I apologized [For what, really?], and then we hugged.
Additionally, I had to wait 25 days past my last day worked, to get paid, and was given neither my Record of Employment, nor my T-4 tax slip, though I made enquiries (which, of course, went unanswered).
For a blue collar class person to have a diction above theirs is the greatest insolence one can show these insecure types, apparently, though they will vehemently deny such.
This quality of being too literate for them seems to be anathema to this place, across the board.
