Union sues to block Indiana right-to-work law - CBS News
Among other things, the union claims the law violates the equal protection clause of the U.S. Constitution by treating building and construction workers and public workers differently from others. The law's provisions regarding construction trades took effect immediately, impairing existing contracts, the union said. Public employees aren't allowed to opt out of union membership to the same degree as private-sector worker, the union said.
"No legitimate state interest is served by requiring public sector employees to subsidize the cost of representation services for private sector employees who refuse to pay any fees to the Union," the lawsuit said.
Union members had protested that the law unfairly makes union members who pay dues also pay for the representation of non-union members who choose to opt out under the new law.
