If you're a skilled salaried worker the law doesn't really consider you to have work hours. Furthermore, you aren't required to be compensated for time you are on-call unless you are required to physically be present.
US labor laws are truly horrifying if you start asking yourself a few "what-ifs." The entire system is built on good faith.
Yeah, I'm juuuust old enough to have a firm memory of when things that were laughably petty were the biggest problems in the world. You mean to tell me the PRESIDENT got a BLOWJOB?!
All the real issues that sowed the seeds for our intractably broken future were sidelined and mostly ignored. Desert Storm, woowoo go world police. LA Riots, oh you crazy minorities and your intolerance for extrajudicial murder. Climate change, what's that?
