I tried calling but whoever answered did so in Spanish, which I don’t speak. It’s a screenshot of a UFW post though.
Signal boosting so that this can get confirmed.
The phone number is the toll free number for United Farm Workers. Both the phone number and the text number respond in Spanish. If you need an English number, OSHA has a number for reporting water and shade violations:
1-800-321-OSHA(6742)
Note that all of these numbers are for reporting violations in California.
As much as it matters that workers in California are getting enough shade, I find it disturbing that employers in other hot states don’t have the legal obligation to provide any kind of shade whatsoever.
