Entry-level remote jobs, worth a look - any advice?

I found several remote customer-support roles that do not need a degree, and I have applied to a few as a nurse's aide. I worked as a nurse's aide before this. The schedules are set in advance, including some weekends. Are there warning signs I should look for?

Thanks for writing this out. I went through something close to it 6 months ago, and it settled down once I kept a simple log of every call and form.
