This is important, right here; healthy boundaries. The best time to set them up is right at the start, too. I've had 3 employers that privided me with a phone and laptop because the jobs involved travel, but I made very clear that work hours are work hours, so when I am off the clock, so are those devices. The respected that each time because the expectations were negotiated upfront, instead of waiting for one party to get ticked off and trying to pivot from that.
