First Amendment:

Unions and Coerced speech

Friedrichs v. California Teachers Association has sparked a dispute that could affect the 


structure of job development in the United States, Rebecca Friedrichs has filed a claim that, 
supporting in any way or giving money to a union violates they're freedom of speech. ''The  suit claims state “agency shop” laws, which require public employees to pay union dues as a condition of employment, violate well-settled principles of freedom of speech and association.'' The case is directly related to an early case  in 1977 ''Abood v. Detroit Board of Education'' that ruled that ''union shop'' is legal in both public and private sectors, forcing
workers to pay dues for collective bargain.
