compensation

I am working for an international logistics German company very big in Indonesia, we have a working contract mentioning a certain amount of compensation should be paid if they fire us or quit on any reason all those stamps and sign by the person in charge. I have document and a chronology from 2014 showing that this company has been doing many not compliant operations documents showing affiliation between this company in indonesia with singapore, hongkong and germany. Many documents showing the morality of the company, add to that emails, communications confirming those. They are now trying to make us look like the bad guys and we are in the procedure of going to court in Indonesia but seeing the gratitude of this company for the hard work that has been done for the last 3 years i would like to know how far can we go in terms of procedures. Can we take them to court in singapore or in europe bringing all the proof we have in hands ?
