The phrase makes my blood boil. Why is the person with lesser power and pay tasked with improving someone who will not be eager to accept aforementioned help? What a crock of shit.
Edit: It seems like the phrase he was using (grandboss) may not have been correct to the situation. My boss screams and cries in meetings, and when I told him this, he said I should manage her. Not sure how this advice was meant to be applied but he also called Simon Sinek “awesome” before so his judgment is suspect.
