Until your next meeting comes around, if you have a few free hours, you can read through this thread, it'll give you some idea of what happened. Be aware that it's a merged thread of about 20 threads, so some of it will seem a little jumbled. Then do a search and read some posts about retro pay. Then take what you learn back to your building and explain to everyone who didn't vote what happens when you aren't actively involved in deciding the future of your working conditions. Fewer and fewer people get to have any say about what happens with their jobs. Not enough of those of us who still do have a voice choose to participate.
