You've Got To Love Unions

They demand that employers have a diverse workforce. But unions operate on the principal of senority, the last person hired will be the first person let go. So the employer undertakes to diversify it's workforce. (Just don't mention the word quotas.) Then when things go wrong, like when there is a strike, it might be the case that the people who are let go first maybe be overwhelming composed of minorities.

Yup, which is exactly what we see at Hydro One. Of course, the union won't say this, but will naturally accuse the employer of discrimination.
