Most stressful is leading up to an in-house seminar. My job was to go to several stores to buy food for breakfast, breaks, and lunch. As well, it was my responsibility to set up room (tables placed by maintenance) as well as organizing all food in the kitchen. I was reprimanded for having volunteers help with the serving. When the in-house seminar concluded, it was again my sole responsible to clean up the room. I had never experienced such high levels of emotional and physical exhaustion.
