Before my ex and I split, she was full time work from home and her company paid $50 of our internet bill. She switched jobs internally to an in-office position, but they didn't stop paying the $50. We split, company still paid $50 of my internet bill. Took damn near three years for them to stop. Only stopped because they ended the entire program company wide. That was the end of my need to keep Mediacom internet; why switch when >50% of the bill is paid by some other entity.
You'd be surprised by how much slips through at big companies.
