If you read the article it says fired. This is also reflected in the title, and in the headline.
https://news.theranos.com/2017/01/06/company-re-engineers-op...
"company has identified a core team of 220 professionals to execute on its business plans, and informed 155 employees that their positions have been eliminated"
The company does not say it fired anyone, they use the word eliminated. Firing usually means someone is terminated for cause. Not that they are being let go because the company does not need them any more.
Because of that, this headline actually feels like incorrect usage: a company wouldn't "fire" 41% of its staff unless they were all engaged in some secret after-hours lab-equipment smuggling ring (and probably not even then.)
