Monday we start a series when we talk to someone with an interesting job to learn more about their day to day life, and give listeners the chance to ask what they've always wanted to know about that line of work. We're calling it “Working Shift.” First up-an ER doctor. You’ve seen it on TV and movies, but is it always that action packed and stressful? What’s a bad day look like? Mary Ella Kenefake is a doctor at Northwestern Medicine Central DuPage Hospital in suburban Winfield and Methodist Hospital in Gary, Indiana, and she’s ready to see you now.
