Forklift 100%, great pay if you work weekends or nights, the certification is either on site or take one to two days, job is easy and in very high demanding til winter, i'd say it's the #1 job for pay and low barrier of entry and workload.
Security Guard is always in need of work, it's piss easy but you will not last longer then a year at most due to incredible boredom
Personal Assistant Can be great or horrible depending on the person in your care, pay can be pretty low but they need workers and hire with zero education and all training is on-site, never done this personally but heard mixed things
Things I would not recommend: Pressbreak operator, factory floor assembly i'd rather commit a crime then be forced to wage at either of those again, at a particular rough time I came close to going out with a tire iron and breaking the knees of my local gyppo drugdealer but luckily I found trade education which is what I would actually recommend, trade will always be in high demand and more workers are retired then younger people aregetting into trades, and that is any and all trades, I am a truckdriver currently studying HVAC.
