Open plan office. Me and three other guys are each situated on a desk, with three comps facing each other, to facilitate easy communication among the members of the staff.
I've been here for a couple of years too (three). It's a suit (or dress shirt) & tie dress code.
But yeah, the boss is very understanding in that we can't just sit on our asses all day, so we can go for 45 minute walks in and around the office, or go to the gym on the upper floor.
That's awesome man. I bet you guys chill a lot in those close quarters and talk about random stuff when you you are able. I know I do, or else I come here to see what everyone is up to or join in on a discussion.
ahh professional attire! Very nice. We definitely have those codes too but they only apply certain areas. HECK YES!!! man I love those kinds of supervisors... especially the one you described. I have had my share of cool bosses too, some not so cool though.
