Cancelling a meeting Occasionally, because of business professionals' ultra-busy workdays, one will be forced to cancel a scheduled appointment to fulfill another obligation. Common reasons for cancelled appointments include, but are not limited to: scheduling conflicts, illness, social obligations, and work mandates (or company-instituted guidelines that impact workers’ schedules and are designed to meet a certain goal). Whatever the reason an appointment is cancelled, it’s important that the individual responsible for the cancellation call the person(s) expected to attend the meeting as quickly as possible, to inform them of the change and provide them with the maximum amount of time to restructure their own schedule.
