The corporate policy being rolled out through the rest of the business has something along the lines of 'find new job or exit the business' for the lowest performing percentage. Can't remember if it's 5% or 10%, but it's what is worked to by management and 'band 3' staff... If I am seen to be under performing, the view would be that either I'm in the wrong job, or that I'm the wrong person for the company.
The views above are my own and not those of my employer.
