The National Writers Guild, a union affiliated with the AFL-CIO, called for that organization to expel thug unions.

I support the campaign, but I think slightly different tactics would do more to stop those unions from protecting violent thugs. I call on the AFL-CIO to adopt rules that an affiliated union cannot make demands that tend to give its members immunity from prosecution for acts of corruption, dishonesty, or violence, and cannot encourage bigotry.

Under those rules, the thug unions will either reform or be expelled for violating them. Either of these outcomes will be better than expelling them directly.
