I've nc for this because it will out me completely.
I work in the head office of a very well known company, but it's frankly a bit of a craphole. Some of the lifts don't work (not a problem for me, but a real issue for staff with mobility issues, as they have to walk further to access lifts, or struggle with stairs) and haven't for 6+ months. The toilets stink, don't flush properly and are often blocked (when we complained, facilities sent instructions on how to flush the toilet 
). On our floor we have 3 toilets for over 100 women. Our hot drinks machine (no kettles, it's all vending machines), break once a week because of overuse (1 machine for nearly 200 people) when we complain we're told they're looking into ordering a new one.
The floors in the office are never vacuumed and desks never cleaned. Allegedly this is because there's 'stuff' on our desks. How difficult is it for cleaners just to wipe them, even once a week?!
The last straw today was when a chair broke in half (back just came off and fell on the floor) when a pregnant colleague was sat on it. Luckily she wasn't too hurt, and baby was fine. But this isn't the first time chairs have fallen apart. Facilities were contacted and said they'd look into it. By 5pm nothing had been done.
It's shit isn't it? The business spends millions on advertising and we're sat on broken chairs. No unions, there's an employee group but they have no power. I'm sick of working like this, it's now dangerous not just unsanitary. But the message is always it has to be left to faculties etc, except they never DO anything!
