Can we still deduct electrical union dues and the additional work assessment fees that we used to itemize on either our Federal return or on the Minnesota return?

My husband's electrical union assess a 3% fee of gross wages.  This is to help the local raise more work for union shops. It is not optional for the people in the union.  Previously this was deductible on Schedule A as "Work Assessment Fees" along with licenses and small tools.  This fee is above the union dues he pays.

Is this still deductible either on the Federal return or on our Minnesota State return?  

Thank you!
