Fast Company this morning features a Leadership IQ study of 32,000 people finding that engagement increases by 30% when people spend up to 6 hours weekly with their leaders. The law of diminishing returns kicks in after 6 hours. This implies quality time and that leaders should have about 7 people each. The report doesn't define the character of time other than it can be in person or virtual. I would suggest it also need to be strengths based, authentic and mutually beneficial.
