A team member is hosting an event and invited several colleagues via their work calendars. Another team member, who was not invited, has been noticeably distracted during several standups. What should the project manager do?

The project manager should meet privately with the distracted team member to understand the root cause of their distraction. This approach addresses the immediate issue with empathy and professionalism, allowing the project manager to offer support or mediate if necessary. Asking the event host to use private communication channels or mark the event as private might be a future consideration for team etiquette, but it doesn't address the current team member's distress. Adding a social-events section to the charter is an organizational process asset update that is too broad and reactive for an immediate, personal issue.
