The principle isn’t really in dispute. It’s putting it into practice where things tend to break down.
The economics stack up in favour of retention. Once you factor in agency cover during the vacancy, recruitment costs, onboarding time, the productivity dip while someone settles in, and the knock-on effect on team stability, replacing an experienced registered nurse costs substantially more than most retention interventions would. Estimates vary, but the figures tend to cluster between 50-200% of annual salary, depending on specialty and seniority.
And yet, in many organisations, recruitment budgets are larger, more visible and easier to get signed off than retention investment. Some of that comes down to how workforce costs get categorised and reported: recruitment spend is discrete and attributable, while the cost of turnover is scattered across multiple budget lines – agency, HR, management time, training – and rarely adds up to one clear number anywhere.
The latest workforce data points to where higher-performing employers are putting their energy: better onboarding, clearer progression pathways, stronger first-line management, more flexible rostering, faster internal mobility. None of this is revolutionary – it’s more that it takes deliberate investment and sustained attention to actually land.
It’s also worth noting that retention problems tend to be locally concentrated rather than spread evenly. An organisation’s overall turnover figure can look manageable while one particular ward, service or specialty is cycling through staff in a way that’s both operationally destabilising and expensive. The aggregate number can mask exactly where the problem sits.
The organisations that end up ahead on workforce stability aren’t necessarily the ones with the lowest overall turnover. They’re the ones that know where their highest-risk retention problems actually sit – and act on them before the vacancy opens up.
