I’m not super well versed on it either, but yes, 30 hours or more is considered full time employment, and businesses that have 50 or more full time or full time equivalent employees are required to offer heatlhcare. But a lot of small businesses aren’t going to meet the 50 employee requirement. The situation I was focusing on was a person with several different employers, none of which is required to offer health care to their employee who works for them for let’s say 15 hrs/week.
Americans would not want the price of produce to get higher but a) it relies on employing undocumented labor and b) it’s very hard to find American citizens these days willing to do that kind of hard physical work.
