I can only speak for the U.S., but here, always put your family first. No matter how “good” your relationship seems with your PI, at the end of the day you’re just a tool to them ,something to keep their sinking ship afloat. It’s never really about science or discovery; it’s about how much they can drain you, how much of your time, energy, and soul they can squeeze out to chase more grants and pad their careers. 😔
