Culture of fear in Vocus NZ - Administrative Support Function Vocus Employee Review

I currently work in a Managerial support based position for Vocus NZ n Wellington. There's no easy was to say this but Vocus NZ office especially in Wellington office, has too many bullies in charge, crating a culture of fear in the workplace. I have seen top management use petty personality issues as a means to fire employees/end probation periods unnecessarily in total contravention to employment law and best practise. There has been a revolving door of victims that have unwittingly been caught up in the unprofessional folly of a number of key managerial staff. Of the people that are not fired, many are jumping ship at a rate of knots, escaping the toxic culture.The people that have not been fired yet/pushed out look depressed and stressed out and are prone to following bad behaviour leads from the bullies in key positions. Management bullies are somehow under the radar or I can only assume that this behaviour has support going to the topper most levels. Do not consider working here unless you hear of a major restructure.
