I have friend who just struggled and struggled to manage her time. She was often caught up by her obligations and cancelled our meetings a few times. The plan was her taking me through one of her portfolios so I could take over, to relieve her and manage her workload. The meeting requests came in and they were either starting way before or ending after office hours. She wasn't pleased when I pushed for all within office hours. I wanted to tell her "too bad, get your bloody act together". I wouldn't be empathetic and cooperative, would I? I was very tempted to ask our boss for advise but I asked my dearest instead and this was the reply:

Dear Boss,
Do you want Struggler-for-time to do "Project 2010" meetings all day, or do you think it's important that she makes time to get me fully onboarded? (I am not sure I mentioned it on my resumé, but I am the centre of the universe and Struggler-for-time is a small moon).
Thanks for your cooperation,
Centre-of-universe
;-)

Thankfully all meetings have been planned within office hours. So I would be able to continue with my own work before and after office hours. Peace.
