What has research into teachers' flow experiences revealed, and how might it be applied more broadly?

A good answer would include the following key points:
-Investigators measured teachers' flow state experiences and what contributed to them.
-Supportive work environments encouraged flow, and teachers who experienced flow eventually created better work environments.
-This finding suggests that the joy people experience at work can create a better work environment for others.
-In applying this finding, employers might poll their workers on the job facets that give them the greatest happiness, satisfaction, and pleasure and then use those responses to emphasize, restructure, or modify the work environment.
