Nobody sees you restock the shelf at closing. That’s why it counts.

Work nobody sees is where the real measure sits, because there is no audience to perform for. Restocking at closing earns no thanks and no photo, so the only reason to do it well is that it needs doing and you are the one there. That is also why it builds something: you are not practising being seen as reliable, you are practising being reliable.

Pick the least visible task on your next shift and do it to the standard you would use if the manager were watching. Notice that you walk out feeling different anyway, and notice who gets handed the keys a few months from now.
