First of all, do they have a policy manual? If so, and if they have any sense at all, it would include language that if someone is suspected to be under the influence, they are to be immediately tested. Obviously you were never called upon to do that. Every company, no matter how small, should have a policy manual. If you were an exempt employee (paid straight salary/no overtime - example, a manager or supervisor), you are not required to be given a reason for dismissal. If you are non-exempt (salary with overtime), you must be given a reason for dismissal. At least that's the way it is in the state where I live. You should also file for unemployment benefits immediately. If you are ruled against, then appeal. Many people get their decisions reversed on appeal with the State agency. You probably have a better chance of getting unemployment benefits than you think. I never thought I would receive any, and I did without an appeal process.
