What reasons can a person draw unemployment if they quit their job?

I quit my job to pursue my doctorate and some entreprenuerial endeavors. However, I would still like to draw unemployment if I can. I was a teacher at a post secondary school and they begen to drop on enrollements which cut my class size and reduced me to one evening class. The company also did away with a regional position I was awarded in total it took $2200 a month out of my pocket. I was with this company for over 2 years. Thanks in advance for your help.

I think they have to fire you and have to treat you bad to collect it.

Laws on unemployment benefits will vary depending on the country and/or state you live in, so this is difficult to answer. In general, if you quit "without good cause" then you are not eligible for unemployment benefits; I don't know if the restructuring of your job would count or not. You would need to talk to the local unemployment office to present your case.

You could certainly try filing. But know that it is unlikely you will receive benefits for quitting. Your past employer will also receive notification of you filing and will have the opportunity to protest. Now you can take a chance that they dont, or at the very least be told that you don't qualify.
You could claim they reduced your position to a non living wage.

You won't like this answer.
You quit because they reduced you to one class per week. So this means you would have had time to pursue additional work or additional studies, and you would still be paid by the school.
So you just took your ball and went home since they won't let you bat first.
In most states you would not be able to draw unemployment. They may have cut your pay but they also cut your time so you do have time to do other things.
Sorry and best of luck to you.

There are some rare circumstances where you might be able to collect unemployment even if you quit - basically it involves being able to prove that you had no choice other than to quit.

The significant drop in hours and in income might qualify, so you could apply although you might be turned down. You don't say how many hours you were working before the hours were cut, so it's hard to say.

Quitting to pursue your schooling or self-employment of some kind would NOT qualify you to collect unemployment. Unemployment comp is for people who lose jobs other than by their own actions, not just who quit because they want to do something different.

you can only collect unemployment if you quit it can show the job was a hazard to your health, that your employer wanted you to do something illegal and you have proof.
