Hello! Thank you so much for being so awesome and volunteering to help us out! If you have to remove yourself from an item you've signed up for, please make sure to cancel it 2 weeks in advance. If you have to cancel on short notice (under a week) we would greatly appreciate it if you could attempt to find someone to cover your shift. We understand there are times when emergencies occur, just know it will be hard for us to find a replacement for you with short notice, which leaves whoever else is signed up short handed for that activity. We appreciate your help. Stay awesome!
