One key to cancelling an event is to do it as far in advance of the date as possible. This gives participants time to revise their schedules and causes the least disruption. You'll be remembered for that. TOP-12 was a monthly roundtable for the Vice Presidents of Human Resources for Colorado's largest employers.
Dear HR Leaders,
Because of summer vacation and business travel schedules, we will not have a quorum for TOP-12 in August. Therefore, our meeting is postponed until September 25th, when we'll have compelling topics—and a full house. (Your membership dues will carry forward an additional month.)
Enjoy the remaining weeks of summer, and call if I can help you or your business in any way.
With best wishes,
:Bill
