Input: I’m a teen and I work at a local small business and was scheduled to work 5:30-11:00pm Friday night. We generally get our schedules Saturday and last Saturday my coworker asked to have my shift this Friday night. I immediately said yes and the schedule was changed that day. Later in the week I made some plans to hang out with friends Friday night.  She texted me today (the day before the shift) telling me she had a wedding to go to tomorrow and can no longer cover my shift. My point of view is at this stage that’s not my shift and it’s her responsibility to find someone who can cover it or call off.
WIBTA?

Also I haven’t responded yet and would appreciate advise one what to do.

not taking a shift back that I gave away
