I can tell that nobody who has posted so far has read the article.
From the article, 88 people had been working at the plant already. One of them for 12 years and one for 14 years. When the service provider they worked for was terminated, a background check was made of the 88 people who had been already working at BMW (for re-employment at the same job at the same facility). 70 of the 88 people were terminated even though they had already been working there for years.
I think that BMW will have a hard time explaining why they were OK for 14 years but suddenly were dangerous.
Reading the excerpt seems to indicate that job CANDIDATES were involved, not (recent prior) employees.
I worked for a company that was bought out and the new owners required criminal background checks, causing several employees to lose their jobs, some after quite a few years.
