I worked at a company where the cleaning lady was considerably more intelligent than most of the managers. But you was held back because her English wasn't really very good yet so she had to take what work she could.

Meanwhile the managers would rock in at 11:30 and immediately go on an hour lunch break. Usually they would then demand a meeting in the afternoon so they could get up to speed with what everyone was doing which was only necessary because they have been AWOL for the past 4 hours.
