The Slack Ghost at 3 a.m.
A California teammate messaged colleagues in Singapore during their evening, expecting quick replies. Exhaustion and resentment followed. The team set norms: delayed send by default, batched questions with clear urgency labels, and a rotating on-call window for true emergencies. Response-time expectations were documented, and dashboards surfaced blockers asynchronously. Service improved, sleep returned, and no one felt punished for time zone math. Customers noticed faster resolution without the hidden human cost.
