Benefit charges: employee claims

• I never employed this individual so how can I be charged?
• When someone voluntarily quits do I have any liability for benefit charges?
• What type of information will the department require in order to keep this employee from drawing benefits from my reserve account?
• I told an employee at the time of hire that this would be a temporary job. Will he/she still be eligible for benefits when the job is completed?
• If I discharge a probationary employee, will he/she be eligible for unemployment?
• What information will I need to provide to the unemployment office if a worker files a claim for benefits?
