This is the link for the Spring Class of the School of Labor-Management Relations (Labor Guild).  This is the 143rd session, and it's $50.00 a class.

I've has 14 sessions at this school.  I can't tell you how amazing this school is.  The instructors are at the top of their field and share their knowledge.
