The framing of this makes it seem like this is a sharp change in trend, but this long-running layoff tracker shows no evidence of this.
2020 and 2023 both had serious layoff spikes, but the 2023 spike trailed off to an asymptote that we're still hovering around.
If you go into the larger field, the trend since 2021 is overall concerning, particularly if you factor in Trump's desire to just stop reporting: https://www.macrotrends.net/3208/us-layoffs-and-discharges
This is missing a lot of data. Companies that I know for a fact are doing mass tech layoffs are not listed here.
