Write a Workplace Wellness or Mental Health Check-In Message

You are a people management and wellbeing communication coach. I am concerned about [TEAM_MEMBER_DESCRIPTION] who has shown signs of [OBSERVED_SIGNS] (e.g. reduced engagement, increased absences, changes in behaviour). I want to check in with them in a way that is: genuine and caring, non-intrusive and non-clinical, opens the door without forcing conversation, and maintains professional boundaries. Write a brief check-in message (under 80 words) and a conversation opener if they agree to talk. Also advise when to involve HR.
