I agree with most of the things but why did you stay for 4 years if you didn’t like it from beginning???
All in all, very ****ty company
PARC contract is crap but also beacuse it’s a crap, you can avoid all penalties if you leave earlier. Just consulting a lawyer, you can find that they don’t have any legal basis for most of the things they ask for.
Also, you signed 7 days off per month, so why would you expect more?
Days off were defined. If it’s not clear in OM, you should consult CAAV flight time limitations document. It was based on UK CAP, so pretty detailed and good (maybe that changed but 2 years ago it was still in force).
And nobody can force you to fly above the limits or to use your discretion if you don’t want to do it. They can try, but as a captain you can and should decline it
Also, I believe that your 19h duty was with augmented crew, so it’s little bit more complicated
