In business, it's tough to be thrown into a new role when you may be good at the work but not as well versed at the people part. It’s easy to point to those who have handled leadership with grace but it's not a skill you learn in short order. And it can certainly be a balancing act when the company continually reminds you profit is the goal.
Fear can be why strong leadership is often as rare as great customer service.
I could be wrong.
