If you're a manager, here are three policies worth promoting:
1. Maintain meeting discipline 
2. Stop demanding or expecting instant responsiveness at every moment of the day 
3. Encourage renewal 
 
It's also up to individuals to set their own boundaries. Consider these three behaviors for yourself: 
1. Do the most important thing first in the morning 
2. Establish regular, scheduled times to think more long term, creatively, or strategically 
3. Take real and regular vacations
