Several years ago I was employed at a 135 charter company for approximately two months. I say I was employed, but the owner requested every employee set up a personal LLC and "bill" him for our services. Although we billed him for our services we would receive a specific amount of money each month (like a salaried employee). The short time I was there I did receive a 135 check ride. Should I waste the valuable space on my resume to list the charter company as an employer?

Less than 10 years, Absolutely.

More than 10 years, Probably.

Omitting anything on a (resume) background check will/is grounds for not hiring and/or firing if you are already hired. Not worth the risk, especially if your are not trying to hide something.

Thanks for the info!
