my commission based job is making me go to traing 5 hours before my shift as well as10 hours a week to do off location traing do I have any recoarse?

My job is commission based and as of this week I have to go on Monday and take a 9 hour class and then on Friday at 7am I have to take a 1 hour class before my 12-8:30 shift the whole time I get only my hourly $8 and no sales. We have to take these classes because our distract is down in sales as a whole while my sales and my stores are still consistently high. Both of the training centers are far, 30 min, from where I work, so 1/4 of my weekly hours are not commissioned on top of extra drive time. This is not what I signed up for and I was wondering if this is legal or not and what courses of action I could take either way?
