Worked for an MSP that basically required 24/7 availability but wouldn't pay for it. They got around it by saying things like your ringer must be at 100% volume at all times, you must be working within 30 minutes of receiving the call, and then you must clock out the minute you stop working. They'd want you to wake up at 2:03 AM, work on something for 5 minutes, and clock out at 2:08 AM. The way the rules you were wrote, you could get in trouble for just about everything except not answering the phone entirely. So guess what I started doing?
