Typically the Project Manager would be notified ahead of time if it’s for a personal leave. If its an unexpected leave, then the PM would need to accommodate and move dates and action items around to the remaining members of the team to meet deadlines. Now what this does is create more work for everyone. Good communication is essential in all aspects especially when a team is down a member.
