Handling calendar conflicts
Would like any tips on how to handle calendar conflicts, when you have two things on at the same time that you would really like to attend, or have to attend, how do you handle it?
For example today I was booked in to attend a health and safety meeting with the general managers, but Friday morning I found out that there was a person coming to visit our Werribee site from interstate, and doing some really interesting work that relates to what we do, and of course it is scheduled for today, and it's really rare to get these type of opportunities. There were three others that could have attended the meeting today instead of me, I checked and one was at a meeting, the other working offsite, and another on annual leave. So with a heavy heart I decided I had to keep to the committment to the original meeting, and very disappointed to miss out. I checked my emails this morning before I left home in case there were any updates about the plans for today, and none. I get into work this morning and find one person's meeting is cancelled and they can attend the meeting - but it's too late, I'm already at work and so can't attend the Werribee site meeting (1.5 hours travel by public transport).
I have another conflict on Wednesday also where I'm missing out on something I'd enjoy doing for work to attend a meeting I need to go to.
How can I better manage these things so I can attend the things I'd really enjoy?
