Let's say you are working as an HR Advisor or an HRBP for an employer such as Northamptonshire County Council, Wirral NHS Foundation Trust or the University of Manchester, but really wish to be performing the same role for an organisation such as BP, Heineken International or The Boston Consulting Group.
From my own personal experiences, blue chips, fortune 500s and private companies can be notoriously difficult to break into, as you have to wait for a specific vacancy to become available and they tend to look for a near identical profile match and fit of sector specific experience. The vast majority of jobs I have obtained have always been in the public sector, be it police, prison, NHS, courts, forces, civil service etc as a 'service' is often more willing to take and train people up into a role. The downside of course is that you cannot work internationally with them.
So whether people unintentionally fall into HR or take the first HR role that can get, can or do people also and overtime often become pigeon holed or labelled by employers by default, such as you are an HR Professional and Practitioner, but an NHS one, a Police one or a County Council one?
However, that can also be problematic if someone is an HR Officer for St. Helen's College of Further & Higher Education, but wishes to then become an HR Advisor for Booking.com in Amsterdam.
