This gave me an idea. Not one I can use at present, so I chuck it out there.
Writing from the point of view of the new person anywhere would provide an excellent vehicle for explaining a location to a reader.
Think about it – the reader is also new to the job/location, so everything going through the newbie’s head is the same as that in the reader’s mind.
OK, perhaps they don’t have the same “Where’re the toilets?” anxiety, but new people, a strange office to navigate around, unusual rituals at break times (does everyone go to lunch together?) and a thousand other questions need answers. There’s also the whole cliquiness of workmates to consider – who gets on with who?
The more I think about this, the more I remember why I hate changing jobs!
