Your boss may well be concerned that managing employees who come in nine-to-five is so much more simple than managing in­dividual work arrangements and that your flexible plan may well mean more work for him.

Bruce Tulgan says that there’s no question managers might need some reeduca­tion. “Managers still like to pay a lot of attention to where people are because that is easiest to measure,” explains Tulgan. “It’s vis­ible. Otherwise, you have to be really good at managing results, and that is harder. But the upside is it’s better for business.”
