"Park Hyatt properties check most frequently. Front desk staff are trained to verify corporate rates. You should be prepared to show a company ID or business card. Hyatt Place and Hyatt House rarely verify."

"I still see a problem for those that don't have a badge and not all employees do"

"1. The policy is that you need to be an employee at the time of the stay. 2. If you booked a U.S. hotel, especially if it's a budget brand or if you had stayed at that hotel before, most likely they won't ask for ID and you should be ok. 3. If you are adamant about not gaming the system for ethics reasons, then you should pay the higher rate. 4. If any hotel does ask for ID, a photo of a company badge generally will not suffice. Given they are going out of their way to ask you, they will want verifiable proof that you're an employee."
