Did the Qatar Academy administrators know about my impending incarceration? If so when?

They mostly likely did from the very beginning, from when the formal complaint was filed by the parent.

Why did my employer -- Qatar Academy -- and its administrators appear to have dropped me like a hot brick on May 1 when I was holed up at the police station? Would they have done anything differently had I been a European or North American or from another native English-speaking region of the world?
