I know, and have criticized, the UFT using our dues monies to subsidize a local rally for Eric Garner and the turds carrying on Occupy Wall Street. I know Randi Weingarten had her eye on a cabinet position in a Hillary administration and used the American Federation of Teachers (of which she is the prez) as a Hillary campaign organ rather than as an instrument to help its dues paying members—teachers. There have been under the table payoffs, expensive junkets on the union dime, and heaven knows what other abuses. I am all for oversight of where union monies are spent and whether they are spent appropriately (to help the people who pay them).
Under the Supreme Court’s Beck decision (1988), union members can demand to not pay the portion of Union Dues that go to political causes...

Of course, any member who did this would be unpopular with the Union Bosses!
