As for the “report” itself, it’s totally unscientific and statistically insignificant bullshit. It’s merely the compiled responses from a self-reported nine-question multiple-choice survey, administered to 301 Seattle “service industry businesses” (you know, restaurants), of which only the 191 employers who said that they started providing sick leave benefits due to the new ordinance are included in the results. So yeah, if EPI can be trusted, about 56 percent of the 191 employers surveyed said that Seattle’s paid sick leave ordinance would increase their cost of doing business. But they weren’t asked to prove it.
There isn’t a lot that grinds my gears more than “studies” that don’t actually mean anything. Although “journalists” blindly repeating the results without making sure they mean anything is probably worse.
