Sitting on the outside now & looking back, it is weird. Sal definitely has the pedigree to turn the company around, and bringing in external hires to turn things around.
Yet the company goes backwards and the talent leaves.
Seems to me there is a vast chunk of middle management causing the problems. Whatever Sal says, they pay lip service to and continue doing their thing, whatever that thing is. The actual billable employees don't see anything changing and quit, further driving down the company overall.
What can Sal do? Well, basically fire everyone above line manager and below C-Suite. You'll loose a lot of good people that way, but you'll also cut out all the deadwood. Then try to hire back in as much talent as you can and rebuild the company.
But that won't happen.
