I’ll have to see if I can find it again, but I swear I got the hours and jobs from the Census Bureau website in 2020 or so.

With the rise of the gig economy and businesses refusing to schedule people enough hours to be considered full-time employees so they can avoid giving them benefits, I’d be surprised if it was as low as 8 million.

I’m getting all kinds of competing numbers even from just the Census Bureau itself, but they all seem to be around the 8% mark - one article saying that it was 7.8% in 2018 and has been on the rise in the past 20 years but notes that these numbers diverge from another census data measurement which put it at 6.3% and falling, while another from a year or two earlier says that based on recently released data from 2013, 8.3% of workers (13 million) had 2+ jobs in 2013.

Either way, it’s a far cry from the average worker. Maybe I’m misremembering it and the stat was about households or something.
