This one is hard to pin down, but it seems (from an inside perspective) that the company goes to great lengths to appear "good", capable, responsible, relevant, modern, in touch with employees, etc - both internally to employees and externally to clients and the public. This is mostly a good thing - good marketing, UX, branding, etc are essential to any respectable business, however somewhere along the way it feels as if what the company has projected itself to be is out of touch with how it really is. It has (perhaps unintentionally) become a little too imaged-obsessed.
The reality is that Aurecon is likely fundamentally no different to any other major engineering consultancy at the moment. As market conditions become ever-tighter, salaries become ever-stagnant, overhead spending is continually reduced and the need for ever-higher performance is imposed on the business (and subsequently employees) in order to survive in these conditions. The sexy way in which the company markets itself therefore appears more and more out of touch with the reality for employees. This in turn breaks trust, decreases employee morale and ultimately probably leads to unnecessary employee turnover and loss of productivity.
I don't want to overstate this, however it is felt and I believe it needs to be addressed. It's a difficult problem to solve but one the company should take responsibility for improving if it wants to last in the longterm.
