It's bad writing, it's an even worse communique from a CEO.
Start with the point. The point is that X percent of the workforce is to be let go. And that it has been already in the works for some time because some people have been let go that day. "some notifications happening today" = we already have a list and we'll go through it as fast as labor laws allow.
All stuff like "best wishes to those impacted by the course correction in our employee base".
Like they aren't just numbers or human resources, it's real people losing their jobs and facing difficult situations with work visas, mortgages, etc. - the same people who have helped build the products they work on.
It's isn't an unfortunate natural disaster but a deliberate decision made by executives, where in the majority of cases it's just that the rate of growth of profit has fallen - nowhere near severe losses and economic trouble.
If he did, he'd be criticized for being heartless. There's really no winning here, I can't blame them for phrasing things the way they do.
