Types of Non-Exempt Work
If you spend most of your time doing any combination of the following, you are entitled to overtime:
1. Analyzing, troubleshooting, and resolving complex problems with business applications, networking, and hardware.
2. Installing, configuring, or testing new computers, applications, networks or hardware based on user-defined requirements.
3. Creating or troubleshooting network accounts (logins) and other business application user accounts.
seems to me that any and all QA work by law gets overtime.
I guess a give away would be the number of lawyers out there looking to sue your employer for you, mostly so they can make a buck, it the law ;)
