Thank you for the information and your question. If you are asking if this statement alone would be support for a "for cause" termination for purposes of unemployment benefits, then the answer is no, not likely. But, if there are other facts that support a direct confrontation initiated by this employee against another employee that was likely to result in physical violence, then that might be enough to support a for "cause" termination resulting in denial of UI benefits. Ultimately, it would be up the the State UI Commission to make that decision after hearing all of the evidence by all parties.
I couched this in terms of UI compensation, because there is no general requirement that there be "cause" to terminate in PA. As you may know, PA, like most states is an employment "at will" state. That, in turn, means an employer may terminate an employee for any, or no, reason and with no notice or warning unless doing so would violate a contract, company policy or is motivated by unlawful discriminatory intent. So, unless the situation falls within one of the exceptions I mentioned, there need be no cause for termination. But again, UI compensation issues are decided differently and could have a different result.
Please feel free to ask for clarification. If none is needed, then if you could take a moment to leave a positive rating in the box above, I will receive credit for assisting you today. Thank you
