If you were fired for "cause", then you can be denied unemployment. When an employee is terminated for cause they are fired from their job for a specific reason. Such reasons include, but are not limited to, insubordinaion, stealing, lying, failing a drug/alcohol test, falsifying records, fraud, disclosing confidential information, deliberately violating company policy or rules, and other serious misconduct. If your employer claims, and can prove, that you were fired for cause then you can be denied unemployment bebfits. And if your actions constituted a breach of company policy, then they have cause.
