If/when my bosses text me unnecessarily when im with my family i always respond with "im with my family" and they get the point and leave me alone. RARELY is a situation one in which can either wait till the next day or be handled by someone there.
My employees otoh are welcome to call me because i enjoy helping and coaching.
Also, always remember if you die, your job will replace you and do it quickly....whereas your family may take years to recover. A pretty sobering reminder of who you are more important to and who is more deserving of your time.
