I agree with the change to cargo pants, or, you could just buy some used swat pants. I doubt you have fashion police if you can wear jeans.
Your choice of pants is killing any chance of concealment. First lesson in CCW
is to tailor your clothing to the type of carry you want to do.
Your job, should you choose to accept it, is to change your attire to allow for concealing the firearm.
It's not like you have a uniform. I would also get the biggest bottle of pepper spray possible, bear spray in particular, and wear that openly on your belt.
If you persist in making it impossible to CCW by clothing choice, you might consider a mouse gun. A baby Beretta fits in a pouch for a Palm Pilot. This can be clipped inside your waist band. Another choice is the Kahr PM 9.
I have a similar situation with running up and down a basketball floor, in some REALLY dangerous areas. My solution was at first to trust the security, and ask for an escort to the car. In these areas they usually had more police then fans, so it worked.
My assignor put me in places a white guy really shouldn't be, the nicer parts of Oakland. After the last year, I decided they can learn the game from someone else.
My solution was a PM 9, but really, the only gun that isn't going to bob up and down and be visible in Thunderwear is a Beretta, baby beretta.
That said, I'll stay with being in a safer job, and, no gun, or a can of pepper spray.
If it's any comfort, I'm just waiting for a wrongful death situation where the
person dies because they were denied second amendment rights, based on a contract of adhesion. Problem is most people agree to the terms of their employment, and only if it's really a monopoly do I think the lawsuit will work.
