I think that if someone works enough hours to be full-time (although, Google says 30 hrs/wk, which is less than full-time) the ACA requires the employer to provide some kind of health insurance option or assistance to the employee. So the post is saying employers have multiple part time employees instead of full time employees so they don't have to pay for employee health insurance. I.e., the employer is shitty and unethical, or "smart" as it's considered in Trump's America.

It became extremely calm and after Obamacare passed that a lot of rural America stopped allowing people to work more than 25 hours a week so they don't qualify for health insurance and it saves the employer quite a lot of money.

Basically they just double up the hires to fill all shifts as stupid as it is. It does save a lot of money

To a degree it's always been a thing cuz Romney care but like it only got worse
