How hard is it to have a job while attending university?

Certainly, it depends on your field of study, and of course, advanced degree programs are going to be more demanding than an undergrad program. That being said, I recently completed my BA in Liberal Arts through Southern New Hampshire University's online program. I have a full-time job, so I only took one course at a time. At 8 weeks per term, it took me 2 years to graduate. Online education requires a certain degree of self-discipline and a willingness to engage with your classmates and instructor without the face-to-face interaction that you get from being in a physical classroom. Also, a common challenge faced by all "non-traditional" students is that the demands of work, home and family still need to be met. I feel fortunate that I had a fantastic academic advisor who encouraged me, kept in touch, and had a genuine interest in helping me succeed.

I wish you the best of luck.

It is challenging but not impossible to have a part time job.
