I am a member of the Federation of Dutch Trade Unions, or FNV, and they are not that progressive. They include the police union and don't make a stand for Palestine. They have made a statement today as a reaction to calls to kick the police union out of the federation. These calls came after police violence against pro-Palestine supporters. The leader of FNV defended the police union in his statement. I think the union has an important place in the fight against capitalism before, during and after the revolution. So when the union is compromised, it means it will be harder for change to happen. I do have hope for the union, but how can you exactly help bring back the revolutionary spirit and ideals?
If there are enough of a movement to remove the police union to warrant a reaction then there must be something to build on. I guess you talk to other union members about the reactionary nature of police unions to grow that movement. I don't have experience here though so take this with a grain of salt.
