Been in to discuss the hours I want to work with my boss when I return from mat leave. There are three of us senior staff who reported to her the other two are higher grades than me but we all worked well together. Any way while i was off they had junior staff act up (has not worked out well) and one of the other senior staff support her.
On my return I no longer report to my boss I report to this colleague to supported my junior staff.
AIBU to feel demoted and upset by this.
