An official statement from Scott Walker's campaign organization claims: “The Milwaukee County Executive's Office expressed policy was that county employees were not permitted to use county time or resources to conduct any political activity. Scott Walker expected everyone to follow the law and made that clear publicly and privately.” (h/t, Capper)
I'm willing to give him the benefit of the doubt and believe his claim. That means that several employees completely ignored their boss' clearly-expressed expectations and willfully violated his policies (and the law), while the boss remained blissfully ignorant.
It makes me wonder how well his current staff are following the laws and policies that are supposed to govern their conduct on the job. He seems to attract corrupt employees who take advantage of his easygoing, laissez-faire employment practices.
