Which one? There's so many scandals St Jude is involved in. A 5 second search on Google will give you at least 20 different ones just on the first page.

some are still hoping to find jobs elsewhere at the WMF

American translation: what happens here is you're officially laid off. You then have to find an open position within the company and apply for it just like anyone else would. In theory, you're supposed to have an easier time and the company will say they'll help you. In theory. You still don't have a job though and none of that is a guarantee. Most of us have sent out 2,000+ applications and get rejected regularly even from within our own companies. This can also succeed in firing you for a higher salary and hiring you back for less because that's all there is. Or as we've seen, switching you from a full time position to a contract one, which does not require the employer to provide you with benefits like healthcare.

That paragraph I don't understand. Why is union busting the only explanation?

Similar to what may have occurred at Rockstar games, to form a union we need to reach a certain percentage of employees to sign on and form it. If that number was being approached (all of this is normally done outside the company and in secret which makes it all the harder to organize) then, if suddenly 100 employees were laid off and don't technically work at the company anymore, then they can't sign on to form the union anymore. Especially if they're able to lay off the leaders and organizers of the burgeoning union, this is incredibly damaging to organization efforts. So the paragraph is saying that an actual re-org doesn't make sense, but it makes sense if the layoffs were attempting to remove individuals to prevent the official formation of the union. Which, while the company might say they'll help you find a role within the company, if they suspect they were part of the union, itçs relatively easy to blacklist them.

the union was apparently formed exactly 90 days prior to the layoff announcement; under california state law (where they are located) “a termination within 90 days of protected union activity creates a rebuttable presumption that the termination was illegal retaliation”

Another reason it feels likely that the goal was preventing the union rather than a reorg. And while potentially true, it would have to be argued in court. And here in America, we don't have public civil defenders to automatically be assigned if someone doesn't have one or anything (ThAt WoUlD bE sOcIaLiSm!), so the "wrongful termination" suit would need lawyers, which are very expensive. And people without jobs receiving severance typically don't have lots of money to pay lawyers, which I'm sure a corporation with lawyers on retainer, especially union busting ones, are aware of this.

Hope that helps explain our capitalist shithole a bit better.

My employer does this too. It is a layoff technically but employees are given the opportunity to interview for another position in the company if they want to stay. If it was a "restructuring" the employees would've been moved to another department and possibly a new role without their consent.
