Do you have a Question about Unemployment?

To Whom It May Concern,
I have given my two weeks notice at a job I have been employed at for 6 months. The reason is that the promises they made me when they offered me the position never metricized. The workplace conditions are intolerable (14 other employees have either quit or walked off the job since I have been there) and the Corporation is being striped of its Choice membership privileges because there are been so many customer complaints and they did not pass recent inspection. My questions are:
1) Under these circumstance and my leaving on my own accord am I still eligible for unemployment?
2) If I was only making $400.00 a MONTH at the time I left how much monthly employment income would I receive? (I was hired as a full time employee and because of company problems and deficiencies in procedure and policies I was cut back to part time status).
3) Does my past employer have to approve my unemployment request?
I have tried speaking to someone via phone, but the lines are always busy and I am thrown out of que.
I would appreciate it if someone could either call me at:(2**9)9********* or e-mail back the answers.
Thank you for taking the time
