As background, state unemployment offices generally give employers a chance to dispute new unemployment claims from ex-employees. In most states, if the employee voluntarily quit or was fired for cause, they are either not eligible or at least the employers experience account is not hit (for each employer, the state keeps a running tally of claims paid to their employees - if the sum is high enough in a given year, the employers rates go up for the next year).
This is all in theory. I don't know what other employer's experiences are, but I almost NEVER win one of these disputes. Most unemployment offices are stacked with people who's bias is always toward the employee. For example, in a recent case, I had documented evidence that an employee was fired for physically attacking a customer! The state unemployment office denied my protest as not sufficient, and to this day I am paying that person's unemployment. Today, I got notice that California had denied my most recent protest. I had sent evidence that an employee was repeatedly warned and eventually fired for constantly being late - day after day an hour or more late for weeks. Nope, not good enough says California. So, instead of paying this person for showing up late, I am paying them, via the unemployment system, for not showing up at all.
Does anyone know if there are any tricks or techniques to be more successful at this?
