Everyone sweeps the floor
The rule “Everyone sweeps the floor” always resonated with me.
This was very much the behaviour and expectations of the person that ran the unit that I worked in some years ago at Apple.
At the time, I was unaware that the badge sticker existed. My boss did mention that they appreciated me always “sweeping the floor” … both in the codebases I worked in, but also emptying the dishwasher.
