Managers as of 2013 (Total NHS staff 1,364,165):-
Managers and Senior managers
There  were  36,360 managers and senior  managers,  a  decrease of  954(2.6%)  since 2012and an increase of 1,039(2.9%) since 2003((an average annual increase of0.3%).
This works out as 2.67%  which I believe is smaller than 3% AS I SAID.
