I have to put in a availability request because of school starting. I was told I have to be available Friday nights Saturday nights and Sunday evenings.my question is do I have to put in a 8 hour window of availability or can I put in a 5 hour availibilty window? I was trying to hopefully work 5 hours a day for all 3 days. Our shifts are usually 8 hours long put I assume they can be less?Thanks
