>The company has not disclosed how many workers were affected by the latest cuts

One of the first things that "progressive" politicians should do if they take power is require large companies to disclose the exact number of firings before people are notified.

That's already the law in the US, the WARN act. It requires 60 days notice before any mass layoffs. The way companies "get around" this is by not actually laying you off, but giving you 60 days notice that you will be laid off and then removing all your access during those 60 days, at the same time they report the 60 days notice of layoffs. It's essentially 60 days severance (plus reporting to the government), which IMO is better than everyone walking wondering who will actually be laid off in 60 days. You can even see that in the email they sent, "today is your last working day" but there will be an email with "details on your [...] termination date". It's unclear to me if this layoff doesn't qualify as a mass layoff (so no warning period needed) or if they just haven't filed it yet, but I'm guessing they'll file it soon enough.

This is how it works in Sweden: https://www.unionen.se/in-english/notice-to-termination

"Even if an employer does not have a collective agreement, they must negotiate major changes to working and employment conditions of employees who are members of a trade union as if the employer had a collective agreement."

Negotiations include getting the lists of positions that will be terminated, number of employees affected, new positions that may be opened during a reorganization, etc.
