Pros

None i can think of

Cons

My experience at Walker Australia Pty Ltd was not good at all. I personally experienced behaviour that felt like bullying, harassment both from co-workers and HR management. These patterns appeared to be part of the everyday environment rather than isolated events. From my perspective, transparency was limited and concerns were often discouraged or kept internal instead of being addressed. Staff wellbeing did not seem to be considered in operational decisions. Based on my own experience, the environment did not meet basic standards of safety, respect, or professionalism. I regret working there!!!

Good for training and development of staff.

Cons

Poor attitude amongst shop floor employees, little regard for their input to the processes makes process maintenance and implementation challenging.
