MsRriO,
You want an attorney who specializes in WCB. You can get representation without needing to meet with the attorney directly.
Google "saskatchewan wcb attorney". You will find a bunch of results to sift through.
I agree that a complain to the licensing board is warranted. But it will not make a difference in the near term. Complaints take too long.
The hired guns are a well trained group.
Don't waste too much effort thinking about these biased people.
If they make you return to work, do it and keep a journal. I'd write a letter asking for provincial (Crown, I think) permission to resume driving. Maybe the attorney should write this letter.

My best to you.
