Just to keep things simple
Over 12 months
Brookfield
800 hours x €80.5 pbh = €64,400
Permanent Employee
Basic Salary €38,000 Sector Pay Taxed Equivalent €36,000 = €74,000
the above FR sector is based on doing 600 hours.
This is how I've worked it out, and for me to be better off on a Brookfield Contract I'd need to work the 900 hours max and become a tax evader.
Both of the above will decrease over time due to inflation, and the never ending dirty tricks by the high pay airline. It might seem like good money to a school leaver, but by the time school is a fond memory, you'll be on less than the above.
In five years time it'll still be 80.5 an hour, and if the industry slumps at all, kiss goodbye to any pay review.
Can only suggest you appeal to become permanent.
It's better to be part of the solution ...............................
