My brother works for Underwriters Laboratories. He used to go in to an office but the company wanted to save a bit of money by not providing offices for their field workers. He now has an office in his home and does all his office work on the computer. He does inspections of various machinery for many companies. He gets paid by the inspection and sometimes they are in another country. They pay all of his expenses and he gets to go lots of places. My granddaughter works at home. She takes claims calls for insurance companies. She reports the claims and I guess the company sends out an adjuster. She also takes pizza orders, sometimes in other states. She turns in the order and it can be picked up in 15 minutes. She gets paid by the minute.
