Background: I'm a swing shift Custodian for an elementary school (scheduled noon to 8:30 M-F). They held staff photo shoots a few weeks ago for school badges and the staff portraits, but the photographer left by 11am; they did retakes today at 10am – obviously I wasn't going to make either session, so I'm left with just my required custodial badge (school badges are not required). So, my Day Lead (essentially my supervisor) told me today that next year I need to make more of an effort to be here, even though I won't be scheduled for it and I won't be paid. Am I wrong for resenting this remark?
