Dramatic mobile phone footage showed protesters hurling projectiles at men guarding the door, labelling high-profile union boss John Setka 'Dan Andrews' b****' and yelling 'f*** the jab'. Bottles and other projectiles have repeatedly been thrown with windows of the CFMEU building with others kicking glass with debris all over the road and footpath. A dog was even kicked as the rallies turned exceedingly ugly, with pictures showing the devastation left by protesting tradies all along the outside of the union office.
