They now now that 33 pilots would like to leave the company. Out of the 33 a chunk have already lined up other employment. Others that can't really tell a future employer that they will now have to wait until June to start. The company can just stretch out the time period before separation so these pilots will resign. Maybe not the more senior guys, but the junior ones. After all, it's not a huge deal. Another job will definitely pay more than a small separation package.
