Wisconsin Gov. Scott Walker said Wednesday that he spoke with Vice President Mike Pence about how the White House can implement on a federal level parts of the Republican governor’s contentious policy that all-but eliminated collective bargaining for public sector unions in the state. President Donald Trump has talked about wanting to weaken collective bargaining protections for federal employees, most of whom can’t currently bargain over wages or benefits, to make it easier to hire and fire government workers and base pay on merit rather than tenure.
