Urgent Can Anyone Help!

Hello everyone,
Wonder if anyone has been in a similar position and can advise.
Im a graphic designer who works 90% in print, 37 hours a week, working for an inhouse studio with freelance on the side. Which ideally I would like to do full time, but hey..needs must.
My 2 collegues and I work in a studio which up to now has sufficient natural light, with inadequate overhead light, just outside an open plan office. Now the whole commercial team (graphic designers included) are being moved.
We were going to be with no natural light and overhead lighting/ventilation questionable. Basically picture a warehouse used as an office. Because we are not happy they have now moved us to where there are 2 windows . . .wait for it, with brick wall of an adjoining building, 4 foot away and 3 stories high.:mad2
All the managers have taken all the other windows in their enclosed offices, ..(because theyre worth it) They seem to think that we require same standards as an office worker and that we need nothing special. 'We've given you a window, what more do you want!?'
I have a meeting with the commercial manager tomorrow morning (who incidentally is taking our old studio space) and wondered if anyone has any advice. I can find nothing relevant to the needs of graphic designers, detailed work. This may also help others in the future.
Thanks I will keep you all posted after the meeting tomorrow.
