I'm going to set aside the workload for a second and look at another side of it. I worked 10 hours a week as a graduate assistant while in PT school. Since I was working for the department, it wasn't much of an issue. I could fit in a couple of hours here and a couple there basically whenever I wanted. However, my wife was also working retail in the evenings when I was home to watch the little one. The reason why I bring that up is this: While you're in PT school, they basically own you. What that means is that there will be times when class runs late, or times when you get something sprung on you at the last minute, and there is no skipping or making excuses. You have to just suck it up and do it. The question then becomes, what do you tell your boss if you get an email saying you have to be at school the next morning when you're supposed to be at work?? This happened to us several times while I was in school. I found out last minute that I had a school related obligation, or I had to stay late for school, and since my wife didn't have a babysitter or another car, that meant she was either late for work or had to call in entirely. In the case of the student themselves having the job, there will be times when you simply can't make your shift because of school-related obligations, and you won't find out until the day of or day before. That doesn't necessarily mean you shouldn't work. My wife wasn't fired for this, but she was written up for attendance because she kept having to call in or be very tardy because of my school stuff. If you do decide to work, make sure you have a job that's flexible, as in REALLY flexible.
