I think it depends on your agency, your division and your manager. I move all sorts of heavy things in the office, put furniture together, pull out my pocket knife, etc. I have asked men in the office to do stuff for me, but to be honest, it's because I usually wear dresses and they're wearing pants. If I had known that this task was coming up, I would have worn pants and done it myself. But my boss doesn't see sex or race. He only cares if you're doing your job.
