You keep repeating yourself. What you need to do is read the posts. I told you, my reasons, I'm not gonna repeat myself again, you obviously have problems reading.
The people that joined or will join COS08 made their choice, they had an option, so they are not "helpless". They made their choice and now you expect me to take a hit to improve their conditions? I am all for improvements to all conditions of service.
I'm sure you won't be supporting an improvement to COS99 that disadvantages your precious COS08. You would do the same, and it all basically depends on which side of the fence you stand.
