Business hours typically follow a 9 AM–5 PM schedule. Philippine business hours are typically 8 AM–5 PM, and many BPO firms run night shifts aligned with US hours. Teams often designate specific "overlap hours" for real-time collaboration and use asynchronous communication (Slack, email, recorded video) for the rest of the day.
