Company drivers, would you haul hazmat for just your normal mileage pay?

As the title says.... company I work for, needs hazmat drivers, for backhaups to support our dedicated account. I have my hazmat endorsement how ever i never told FM i got it, nor do I plan on it. You guys receiving extra pay for hazmat? If so, extra per mile? Flat rate amount of x amount of dollars per load? Just curious on what the "industry standard" is

 

Got it about a month after I was hired

 

I also run for a mega, with a very small pool. I knew from the get go they don't pay extra, hence why I never told them, nor will I run hazmat for free. I was just curious about others

 

That's my entire view on it. I have a lot of people telling me you don't get extra as a o/o so suck it up. I beg to differ, as a o/o you have more leverage...to a extent. I actually have a great working relation with my fleet supervisor, and often times find myself going over my FM's head. He absolutely agrees that hazmat should pay more, whether it be an additional xx cpm, a good flat rate additional pay per hazmat load, etc. You would think this guy was a lifetime driver himself, however he's never driven a truck in his life....his father drove an saw how much sacrifice it takes and made a promise to himself that he will never treat drivers like how his dad was treated. Some decisions are out of his hands unfortunately. If it was up to him I'm confident in him that he would pay very well. I just find it mind boggling how companies want all this but aren't willing to pay. I'd like to say it's safe to assume that the carrier charges extra for hazmat, so why not pass some of that off to the driver who is making the money for the company?
Not to mention, out of curiosity for one week I treated each load as if it was hazmat just to get a feel for it,(it's common for me to haul under 1k hm, so I'd just use that hm sheet an pretended it was a placard load) looking in the hazmat book to verify placards an such, hazmat routing, etc.....it can be rather time consuming
