The lady who is obsessed with having the nasty, flickering lights on so that everybody else gets a migraine. You could be working there perfectly happily, she marches in, slaps the switch without asking if it was off for a reason (yes, Margaret, it's off because wearing sunglasses or arc welding masks in the office is frowned upon, strangely enough) and everyone recoils like vampires at sunrise, stays for two and a half minutes and she then walks out again, leaving the fucking lights on. Repeat throughout the fucking day.
And the person who instigates the 'no eating at your desk' rule. Whilst eating her own lunch at her own desk.
Or the 'Well, we've never had anybody who wanted to take a lunchbreak before.' That's because we used to be able to eat at our fucking desks, Sharon. It's a legal requirement, by the way. I'm prepared to wait until the 6th hour to take it as a way of showing willing, but I am fucking taking it. Every last second. Yes, my contract does say, as is legally required, that I am entitled to a break of x minutes. It's not a fucking serving suggestion for a period of time in which I am going unpaid. It's The Law.
Or 'staff are not permitted to leave the site during the day for any reason without express authorisation from the Director'. Excuse me? I'm confined to barracks during my lunch break? No, I will sign out and back in to the building and vary my hiding place on a daily basis so I'm not hunted down after ten minutes for something incredibly urgent that is needed right now for a week next Tuesday.
And finally (until I think of something else) 'We prefer you to stand for the duration of your compulsory overtime. It looks better that way'. Excuse me? It's more aesthetically pleasing to a non specific entity to have somebody with a Protected Characteristic (Disability) stand and lean over a table for 4 hours on top of their normal working day (in heeled shoes, naturally) than it is for them to sit at the table like a normal human being and be capable of walking to the bus stop?
