I had a manager once ask us to give 100% during a production incident, including over the weekend since we'd worked into Friday. On Saturday I started to realize the extend of the damage and told everyone to pace themselves--I took Sunday off. The problem was extensive data inconsistencies with duplicates requiring application of heuristics yet to be developed in an area our team didn't have expertise. It took months to complete. The last thing you want is for tired burnt-out folks making sweeping production data changes in a hurry. The manager's idea of helping was repeatedly asking in the dev chat channel, how's it going? When will it be done?
