Legal Question in Employment Law in Pennsylvania

You may be entitled to UC benefits due to the unilateral reduction in your hours. You should call the Bureau of Unemployment Compensation to see if you qualify for this benefit. Otherwise, you have little remedy. Your employer is always free to change your hours and your rate of pay. An adverse employment action cannot be motivated by an illegal motive to discriminate against you due to sex, age, ethnicity, disability, etc. Otherwise, your employer is frre to make such changes.

This answer to your legal inquiry is based upon the limited facts stated in your question. Accurate legal advice is based upon an exchange between a lawyer and a client. The lawyer can then ask about other facts that may change or confirm the answer. Without that exchange, this reply should be considered limited in value. You should rely on this answer only at your own risk. Direct consultation with a lawyer is always recommended. Answering your question does not create an attorney-client relationship.

Without a union, the employer can do this. I do agree you may be entitled to UC.
