Oh, please. These pensions are impossible now, but that's because of decades of underinvestment and out-of-control health care costs.
Also, the workers didn't promise themselves anything. They made a deal with their employers. The employers didn't have to agree to anything. They did, and those deals should be honored.
The employees getting the pensions are not the same ones doing the negotiating. By your theory, government employees would always get what they wanted and therefore never strike, but that's demonstrably not the ase.
