I worked at a company where it was decided that the tech support department had a bunch of college drop outs and nobody had a business degree so they had to hire some. A few MBA guys were hired. These guys had MBAs straight out of school with no experience outside some internships... and man it showed.
Their first job was dealing with managing a schedule for about 25 people who manned the the tech support line 24/7.
They just couldn't wrap their heads around the idea that on the spreadsheet if you schedule someone on Friday until Midnight... starting them at Midnight on Saturday doesn't make a lot of sense / they would be working 20 hours in a row.
It's was horrible working with these guys. They embodied the "I'm business guy and I made my decision for business reasons and you should follow them."
Eventually I (worker drone) took over the schedule because what became known as "the MBA team" couldn't handle it / had no idea how to balance priorities and etc.
I'm sure there's some great schools for business / MBAs but I really wonder what they teach at those schools if just understanding simple hours, math, responding to emails in a timely / professional manner isn't it. It was almost like the old FedEx advert: https://www.youtube.com/watch?v=NcoDV0dhWPA
Perhaps they should all be required to go manage a McDonalds for a year or something?
