Was accused of being a drug addict without a single test by Tigerair or CASA or after numerous requests for proof was completely denied
Ok that's different to the original story (about 80 pages ago) but thats ok, you didn't get to tell that story.
Accused of drugs with no positive drug test. Refuse drug test. Fired.
I was of the impression that refusing to comply with a drug test was the same as a positive outcome as far as 'most companies' are concerned, as well as CASA. That would be adequate reason for dismissal right there.
