Work-from-home support roles hiring this month

I found several remote customer-support roles that do not need a degree, and I have applied to a few as a machine operator. I worked as a machine operator before this. Most want a quiet workspace and reliable internet. Are there warning signs I should look for?

Thanks for writing this out. I went through something close to it 12 months ago, and it got easier once I kept a simple log of every call and form.
