partition furniture...will be on site tomorrow. Supposedly the electrician did his work today. From what I was told by the furniture people it's a non-metallic pole with no division for power/data.
I'll find out for sure when I get on site. I'm sure that the electric is going down the same pole. Potential nightmare.

How would that be a potential nightmare?

We usually run into power poles that don't have separate compartments for power and low voltage - so the electricians just use "bx" cable and we go in alongside of them. Yup, the Cat-5 runs above the T-Bar, supported by J-Hooks or cable tray, and then drops into the top of the pole.
Bigger problem is they never give us enough power poles to accomodate the number of drops in the cubes. They want fewer poles for esthetics, but then they want 3 or 4 jacks per workstation.

About the only disaster I can see here is that the top of the poles are going to look like hell because they are exposed.

In South Dakota there isn't one inspector who will let an mc cable and data cables run in the same raceway. And just the electrician in me I would much rather bend pipe across an open ceiling to the top of the power pole and run my power in from their same with the low voltage. If it's exposed two conduits would look much better than a small bundle of cat5 and an mc strapped up to sag and not lay striaght. I kinda like bending pipe though.

Ask them to quote the Code Article that prohibits that. They will have to, they can't make things up on their own. Then you both will see that there isn't any prohibition against a listed cable assembly (such as NM, MC, AC, TC) in the same raceway as communications, nor should there be. What's the difference between running them together in a wall bay?
Open conductors in the same raceway with CL2, CL3, Class 1 or communications is another story. Perhaps that's what you guys are thinking of?

Around here in a lot of big boxes they run MC cable and cat 5 in the same power poles and even cable tie them together. Is this a code violation?

The Code doesn't care if it looks bad or even if it works. The entire purpose of the NEC is safety. It provides minimum requirements for the installation of electrical and electronic equipment and wiring to protect people and property.
So if you are looking for how close can I run my CAT6 cable to a lighting fixture you won't find it. That would be a design issue.
