I work for a medium size company in he UK
Staff handbook says all leave must be agreed by your line manager and will be approved on the basis of business need and general staff numbers/ work coverage etc - all fine, been here for 8 years, never an issue. I'm in a team of 5 and collectively with our line manager we manage to get holidays to suit everyone etc.
Line manager left in June and we've got a new one from a different department, no issues, we all get on well.
But, I've asked for a week off in the autumn for the school holidays. LM replied asking when I was away and where was I going, I thought it was just a casual passing interest type question, replied with details of our plans.
They've now rejected my leave request because they don't think I'll be fit for work Monday returning from Tenerife on a Sunday on a flight that lands at 10.30pm (at an airport 20 mins from home).
I've not replied yet but AIBU for thinking it's up to me how I spend my annual leave and it's up to me to decide whether something is achievable whilst being ready for work the next day?
