IF SOMEONE JUST CANNOT FIT IN; FIRE THEM!
The purpose of this note is to reassure you that it is OK to fire a volunteer when all your efforts to help them fit in, or fix a behavioral issue are just not working out.
There is no law, or anything to stop you from firing a volunteer.
Now please do not get me wrong, our first choice should always be to give a person a chance. But sometimes a volunteer just cannot meet simple expectations or objectives, and they cause more damage than any good they might do. You are left with no choice but to fire them!
