MOL has said many times that he wants a significant percentage of his work force (think it might have been as high as 60% quoted) on contract. Firstly it transfers all of the administration hassles to the contractor (no PAYE/administration etc for FR to worry about). Secondly it means that downsizing can occur at a moments notice without the costs of redundancy nor having to abide by various labour laws. It also makes it much harder for the individual pilots to group together and try to improve their T&C's since their is often a difference between the various contracts in circulation. At Dublin in particular bringing in contractors was a tactical move to get back at the permanent pilots that held MOL over a barrel for their conversion courses from the 200 to the 800. It also served to destabilise their efforts in forming a union.
Whilst the Brookfield contract may appear on the face of it to be reasonable you need to factor in that one day the phone might not go and your services are no longer required. The other benefits that aren't included in your remuneration have been discussed ad nauseum and it really is down to the individual to "price" them into the equation and see if what is offered on the table stacks up.
