Some facts:
* The number of job openings declined to 10.4 million
* Hires decreased to 6.3 million
* Separations were unchanged at 6.0 million
* Within separations, the number of layoffs decreased but the number of voluntary separations increased to 4.3M
within the number of voluntary separations (see https://www.bls.gov/news.release/jolts.t04.htm):
* Private industry quits up from 3.87M to 4.1M (increase of 140K workers), primarily driven by Accommodation and Food Services (157K more quits. Wow.). The other separations were not particularly meaningful. Next biggest was healthcare (+30K). Perhaps this is due to the traveling nurses phenomena. Everything else was noise and separations decreased in all other industries (in aggregate) other than Hotels and restaurants.
This does point out that the Hotel and Restaurant industry is still being hit hard. Note that just because something is a "quit" doesn't mean that it was voluntary per, se. It could be a buyout offer, or people quitting who have had their hours reduced or are earning much less in tips to keep working. Hotels and Restaurants are definitely hurting due to ongoing lockdowns and reduced travel.
Note that in Information, separations declined. In Professional and Business services, separations went from from 697K to 706K (+1.3%). That is statistical noise.
