The outside view of Axon? The City loves it, and Mark Hunter is in business primarily to make money for his shareholders, not to be loved by his employees.
Its success is based on:
a) maintaining high rates of occupancy and
b) keeping a tight control of its costs.
The former means that consultants' career aspirations will always take second place to filling a billable role; the latter that pay rises, expenses, and other employee policies will never favour of the consultant. You probably already know how difficult it is to get authorisation for training courses (still 3 signatures?). Training time is non-billable time. I also found it cliquey and the so-called "support staff" anything but helpful.
Yes, there is plenty of work and the success will continue for many years to come. That success needs a workforce that is happy to go from project to project, maybe doing the same thing repeatedly - and if that is you, perhaps you should consider contracting.
I don't believe that from an employee's perspective it will ever change in his/her favour.
