Times 6, more lead to your pencil. I'm with you on this - I have been at 5 serco units ( have we met in a previous life?) and have no qualms in acknowledging the abilities of their staff.
Yes, serco does have it's problems - mainly image based, but their heart and intentions are good and true. As for the share price, well that's just market forces, and what goes down will without doubt go up!
