Union construction workers do a whole lot of standing around.

As one guy sits on a wooden box tapping on a cinder block with a hammer, four other guys stand around him and watch. This goes on for about 20 minutes. Then they walk back over to their truck and point at things while talking and sipping water. Then they all walk up and back taking turns pointing at stuff and more talking. An hour has gone by and now they’re back to tapping on the cinder block.
