So yeah, I've definitely experienced a problem with a team member in the past. I can recall from my previous job, my most recent job, I had a coworker who had some issues with the calendar and scheduling meeting rooms. I had a customer come in that had their meeting room scheduled for a certain time, however there was another conflict in the schedule book that my coworker had put in there. So I quickly assessed the situation, acted with professionalism, was apologetic and empathetic towards the customer, and then made sure to get them situated into a different time slot that worked best for their schedule. After that, I followed up with my coworker regarding the situation and made sure that this wouldn't happen again by providing them any support or resources they needed to make sure we were all on the same page when it came to scheduling and booking the meeting room.
