Legal Question in Employment Law in Pennsylvania

If your question is whether your employer can subtract the equivalent of an unintentional shortage from your earned wages in your paycheck, the answer is no. Such a subtraction would be violation of the wage & hour law.

If you are asking whether you can be fired, suspended or otherwise disciplined, the answer is yes. If you do no have a written employment contract and you are not a union member, the process will be governed by the employer's handbook/policy manual. Such policies are very flexible, can be changed at any time, and probably don't give you much protection. Such policies, however, should be appled uniformly.

Your entitlement to unemployment compensation if you are/were fired is an anlysis that requires a lot more facts.

If your employer believes the shortage is intentional, it might seek to refer you for criminal prosecution.
