" LegiStorm, a database service tracking the congressional workforce, found Klobuchar had the highest staff turnover rate in the Senate from 2001 to 2016. "
from Huffpo:
“I’ve heard people say she’s tough to work for and I sometimes cringe when I hear it because I rarely hear that said about male bosses in Congress despite the fact that half of Congress is tough to work for,” said Tristan Brown, a former legislative aide who called Klobuchar “probably the most brilliant, hardworking person I’ve had the privilege to work for.”
One morning several years ago, when most of the office staff was running late — the ex-staffer couldn’t remember the reason — Klobuchar wrote out tardy slips and placed them on each missing aide’s desk. The staffer recalls incredulous bursts of laughter as her co-workers arrived one by one to find the notes, but Klobuchar was deadly serious. An aide whom she called into her office walked back out in tears.
“She was constantly lighting new fires,” a former staffer said, sometimes at the expense of focusing on legislative work.
“When you have people who don’t want to work for you, you can’t be as effective,” the staffer added.
