FR don't do salaries. They pay per scheduled block hour - thats how much flying they decide to give you per month. You have a month full of flying - great. A month of stand bys - no so great.
You have NO control over what you get given, and so No control over your monthly pay.
The rate of pay varies depending on your level of experience too, so it is impossible to give a 'salary'.
However, your first 12 months of flying should bring in around 25,000 to 30,000 euros.
Not many holidays to spend drinking in Didsbury though!
Don't forget the £32,000 euro TR too...
