My question involves labor and employment law for the state of: New Jersey

I was recently lost my appeal to the decision of UI determination. Now in the letter that i was told that the as per N.J.S.A 43:21-5 the burden of showing good cause is on the claimant and the test is whether was "cause sufficient to justify an employee's voluntarily leaving the ranks of the employed and joining the ranks of the unemployed."

Here is the story - I was told by employer to resign my job (yes my boss admitted during the appeal hearing that he asked me to resign) because i tried to solve my schedule problems that i was facing while i am in college. The employer kept on asking me to work extra hours or even stay past my scheduled shift and due to this reason i use to get late to college even not make to my classes some days. In the appeal i mentioned that i was always in impression that i had to work my scheduled shift and employer cannot force me to stay my past scheduled shift if i don't want to and there were times that i had no choice when i was working in office by myself and no one would come relieve me on-time. Since company wanted to run office 24/7 they should accommodate more staff instead of asking people working over time. Now some rewind (in nov 2014) there was a reduction in force in our office and company got rid of 35 employees and kept only 6 of them. I was one among 6 of them. The challenge was that the company still wanted to run office 24/7 and make us work like animals. The work that was done by 35 employees was strictly to be covered by the six employees that were left in office. Now in feb 2014 one of the employee went for sick leave and took 2 months. During that time i was forced to work extra hours and even come to work after my college hours. I approached HR and my boss 4 times asking if they could resolve this problem because the amount of work vs the no. of employees is (too much vs less employees) and i cannot work extra hours as i have college. Company was completely aware of my enrollment in college and yet they could not resolve any problem. I was told that there will be a shift bid soon and then they will hire more employees which never happened for 2 months. During that time my performance in college was affected and i approached my boss again. I asked him if i can apply for educational leave but HR department said that since i was non-union employee i do not get any such option. Then i approached my boss again and this is when he sat with me asking what are my expenses (college bills, rent bills, and even insurance) and he tried to point me that if i have saved some money then i should use it towards my expense unfortunately he cannot do more than that and only option he has for me is to ask me resign from job. Now i am fighting for my unemployment as i resigned due to schedule problems and employer is fighting that i should not get my UI. I would appreciate if someone could advice.
