"What I would do depends on how my colleague's tardiness affects me. If their delay causes me more work because I have to take up their slack, I will address their lateness the first time they are late. I would ask them in private why they were late, showing that I was genuinely concerned and wanted to help in any way I could. If my colleague's consistent lateness didn't affect me, I would not say anything since that is my supervisor's job to address the issue."

"If their tardiness were impacting our team, I would ask them to have lunch and try to connect with them to better understand if they have something going on in their personal life to cause them to be late. Perhaps they are having transportation issues or haven't found a better route to get to work. I would express my genuine desire to help them understand the impact it has on our team and try to offer support or solutions to whatever it is that's causing them to be late. As a more senior employee, I could help coach them on how to have a conversation with their manager if it were a situation where they needed to attend a doctor's appointment and flex their schedule or needed to temporarily modify their schedule until they got their affairs in order. If the behaviours continued and negatively affected our team, I would approach my manager to ensure they were aware of the situation."
