OK having got you this job (OK you may have had a small part to play

) you sure as hell ain't gonna lose it now!
Way I see it - you've obviously made some major changes, forced the lazy bastards to work and as a result they've walked - not you're fault - you just need to proove that productivity has increased, or that laziness has decreased.
Don't worry about it - the between my boss changing job and me taking over on the Monday our cash forecast went from £4m positive to £2m negative - I had some serious sweat patches that day I tell ye! Just got to remain calm and look at it from angles (and work out that someone forget to submit their cash forecast) - it all comes good in the end!
