"RIF" is US jargon; you can see that ~0% of worldwide Google usage outside of North America for "RIF" is "reduction in force" [https://trends.google.com/trends/explore?date=now%201-d&q=%2...]. A tiny amount (<<2%) of usage in UK, Scandinavia, Poland, Australia (possibly mainly from US multinationals).

There is zero reason to adopt managementspeak jargon, or its 2022 neologisms "impacted"/"affected"/"displaced". Just say "layoff" (n) / "laid off" (v), already.
In the very unlikely event [in tech] you actually needed to say "temporary layoff", you can easily say "temporary layoff".
The language was working fine for decades and there's no reason to pander to management euphemisms. It harms clarity.
