Of course they wouldn't put a number on it. If they did, you worsties wouldn't take the bait and send in a 98% vote for in favor.
There was a third list only because people were hired after the snapshot was taken and weren't considered by the arbitrator. Remember, by the time Nicolau came up with his abomination, there were no longer furloughees on the east.
Since then, that third list is simply present at the bottom of the east list, as they are all working.
Should USAPA treat the west furloughees like the west presented the east furloughees to Nicolau? That is, bringing nothing to the table and therefore should be stapled? Is that what you are asking? Or, would the west furloughees prefer to hit the arbitration table with their DOH?
