I don’t understand why they were so anal (excuse the pun!) about people taking too long while going to the toilet. I don’t if it was pressure from above or something else.
My way of looking at things is that happy workers are better workers. If you operate under a climate of fear, then no one cares about the outcome and just wants to come in, do the work and go.
You just have to treat people like people. Like you say, what’s the point in getting an MBA just so you can monitor how long people spend in the bathroom! It’s madness!
