Where I am now each teacher has their own partitioned desk space in the teachers' office, where you can drink any beverage of your choice. I bought a kettle for the room, and there is a drinking water machine and fridge as well, so we are quite well off really. This is for the FTs, but the Chinese staff come in as well at times, we have a fairly good relationship with them, so it's all good. Students, customers and others are kept out though!
My last school wasn't so nice, no desks for the FTs, but we did have cupboard to put things in. Not locked though, and the boss and his wife used to rummage through it at times!
(No privacy in China either!!)
