Unless it is an emergency,
No.
Why?
Because your staff considers
you changing a staff meeting
an indication of your priorities.
They will feel you value them less
than the event you bumped the meeting for.
The more our managers value us,
the harder we work for them.
That’s true at all levels.
So if you have to re-schedule,
you better ensure
the event is pretty DARN important.
What if you expect to get more information
a day later?
Then have two short meetings.
Use the first as an opportunity
to let your staff speak.
