The study looked at how wages differ between public and private sectors in different parts of the UK over time. Public sector wages used to be higher, but they are getting closer to private sector wages. In expensive areas like the south-east, public sector workers are paid less than private sector workers, making it hard to hire people for public jobs. Public sector wages don't change as much based on where you live compared to private sector wages. This could cause issues in some parts of the UK for public services. Changing public sector pay could be expensive, so other ways to make public jobs more appealing should be considered.
