I don't intend to be dismissive by sharing a bunch, I ate a bunch of downvotes so I should share something. But, there's no singular, like, Wikipedia article for "tech layoffs spiked significantly in 2022 and have stayed elevated" - so this is a mix of informal and formal and academic and business news that treats that knowledge as implicit while discussing it.
(I am deeply curious what valhalla you are at that skipped this so much that it was a foreign idea! N or A, it must be one of those two)
Sure, it waxes and wanes. 2022-2023 were probably above average layoff years, while 2020-2021 before that were probably below average years. I think layoffs have fallen since 2023 rather than staying elevated, but I haven't attempted to quantify that.
