Whatever you do, when you meet the CP, be humble, admit your mistakes and don’t take your scheduling “act” there. I advised a probationary pilot who got crossways with a captain the same thing, knowing his hearing, which as he was on probation I couldn’t be there, wasn’t gooing to go well. He walked in, told the base CP, the captain was a problem. It ended quickly.
A disciplinary hearing resulted you eating a slice of humble pie probably won’t be a PRIA item, termination for cause will be.
