This has been happening since the start of September and it’s really starting to piss me off. I work full time as does my colleague, 9-5.30pm roles. Colleague is relatively new, perhaps 10 months. She has her lunch at her desk at 11, goes out for an hour every day for a walk and then leaves just before 3 to collect her son from school to get back to the office for just before 4. She’s meant to be using her lunch hour to collect her soon, not have 2 lunch hours plus eat at her desk. It’s really, really grating on me. Should I live and let live and get over it or am I in my rights to say something?
