I have one colleague who just royally takes the piss with lunch breaks.
Say they leave the office at 12:30, they come back at 1:30 but with their lunch which they then heat up / prepare and then spend 30 mins eating at their desk whilst reading or facebooking. They only do this when both managers are out of the office. I am not this persons line manager, just sit right near them.
Twice a week they have to pop home to let their dog out and they live about 20 minutes away. They're often 90 minutes or more but again this happens to fall on days that both managers are out.
I just feel that if it was the odd occasion its fine but when it is 2-3 times a week (even worse when a manager is actually on annual leave!) it actually makes up a lot of time!! I tend to bring lunch with me and go for a quick walk at lunch time just to stretch my legs.
AIBU to either say something directly to them or even tell a manager?
