big farms have a lot of workers, mostly migrant workers who are heavily exploited
fruit picking is the main one that comes to mind

Depends on the crop your growing, but yes, at lot of farms employ workers, often seasonal migrant workers for the harvest. Also dairies and meat production farms also function more like a factory than a traditional farm and employ dozens of not hundreds of people.

Cereals though can mostly be planted and harvested using large machinery and so often are just run by one family.

i was gonna say that a proportion are mechanized and don't need much labor, but looking at some job listings it seems like farms of every size and type still try to employ seasonal labor.

fuck that's grim we need to return to villages i thought the whole point of isolated farms was they didn't need the labor as much, no they just make laborers drive ridiculous distances for shit pay and conditions
