I would never even ASK if I could bring my ball. I simply sit on it.
And I work with lots and lots of former military and some active reservists. If you don’t point it out, it takes a lot of people a while to notice.
Although, when I had no workspace and rolled it out to the hallway kiosks, it got a lot of attention.
Many of the guys want to try it.
I’ve been sitting on the same blue ball since 1999. I just delfate it and move it in a box.
I did have one boss who did deflate it at night, and the normal guy thing is to come up behind me and kick the ball.
So, you must have a sense of humor to sit on the ball.
I have thought about a Balimo chair too though. MD has one that I tried, maybe I can borrow it for a week or two to see if I like it enough to buy one.
