Regulations and Procedures: Forgery

There is an assistant director at a county children and youth services who is signing caseworkers names and putting her initials next to their name on letters that go out to families telling them there is a referral on their family for physical or sexual abuse. Caseworkers have been unaware that she is signing their names until recently because these letters were never sent out until now. Families are calling caseworkers and asking about these letters because their name is signed on it but the caseworker doesnt know anything about it because they were never told she is signing their name. My question is...is this forgery and is it against the law?
