"Employee's who work for the NHS (and in most public sector jobs) are onto a good 'screw' compared to our private sector counterparts,"
They may be on a more equal footing now, but it was not so long ago that NHS techs were paid paid considerably less than their private company counterparts.
Those of us that have have been around a long time, will remember paying to have student/junior techs to go to college and get their ONC/HNC. Once achieved they promply left for industry to a better paid job.
In 1972, I left a well paid industrial job (£32 a week) to start in the NHS as a qualified tech (grade 5) on £20). Why? Because I wanted to improve myself and reach higher goals.
