There's a big difference between being restless -- i.e. going for a bunch of job interviews -- and actually switching jobs.

Articles like this highlight the very plausible idea that the post-Covid reawakening will include a lot of "Wanna hire me?" conversations. Perhaps even over meals with someone's expense account picking up the tab.

But as other posters say, a lot of that may be momentary flirtation. Plenty of exploring; not so much movement.
