As well as the pandemic causing employment uncertainty, as @Andrew_nenakhov says, there could be a temporary downturn in the number of resignations in the last year and a significatnt portion of this "great wave" is potentially the numbers catching up again. I also think that because a lot of people lost their jobs as a result of the pandemic, some industries moreso than others, the market may also be temporarily saturated (at least more so than usual) with candidates at the moment, which will dampen the number of resignations. Having said that, I personally am receiving just as much recruiter spam as I was before.
