A while ago, Beth (who I first worked with in the Exchange group on DST and now on customer satisfaction improvements) told me a story that she'd heard from her husband in the past. When people leave a large company, it’s like when you remove your hand from a swimming pool: you don’t really notice a change in the water level.
But in some cases, people see the water line drop significantly when great people move on to a new role or leave a company.
I saw the water level drop today. Twice.
