If they try it again they'll struggle to get many from the pilot group to sign up for it unless they sign off the 25 year housing that was agreed last time around.
SLS is just a management game:
"Look how clever I am. We had this problem and I managed to help fix it".
"Yes, well done you - have a promotion / bonus".
2nd time:
"Look we have this problem and I managed to help fix it"(best I don't just copy the last guy but change it somehow in a really clever and original way)
"Yes, well done you - have a promotion / bonus... and btw I loved your twist on a theme, shows you're thinking out of the box!"
I took SLS last time and the time before. The first time because it seemed necessary, the second because I fancied an extra 3 weeks paid leave. Next time I'll have to bite my nose off to spite my face and not take it as they've proved themselves to be untrustworthy. A sad state of affairs.
