The Case for Nurse Retention in Mental Health Care

In recent years, the conversation around the UK mental health and social care workforce has focused heavily on recruitment. Vacancies keep rising, services remain stretched, and the pressure to “get more people in” is constant. But the reality is that recruitment alone won’t fix the problem.

What’s often missing from this conversation is a focus on retention, the more sustainable strategy that could make all the difference. Retaining experienced nurses doesn’t just save money and time, it builds stronger teams, improves care, and establishes healthier workplaces. People in support don’t want to form connections and have trust broken by staff in revolving doors, and staff don’t want to feel forced into these revolving doors to begin with.

Let’s take a closer look at why keeping staff is every bit as important, if not more so, than hiring new ones.

A Workforce Under Pressure

There’s no denying that both recruitment and retention are under strain. Across the UK, mental health and social care services are facing significant workforce challenges as NHS England reported that around 43,600 full-time nursing posts were vacant at the end of 2022, that’s roughly 1 in 10 roles. In mental health care, vacancies are often even harder to fill. The Royal College of Nursing (RCN) has repeatedly raised concerns about nurses leaving the profession altogether, citing an “early exit crisis” that could derail planned reforms.

It’s not just a numbers game. The cycle of hiring, training, and losing staff creates instability that’s felt across the system by teams, people in support, and leadership alike.

Why Retention Deserves More Attention

Long-serving nurses bring experience, trust, and deep understanding of their communities and the people they support. That kind of continuity is hard to replace, and easy to lose when turnover is high.

High staff turnover also affects morale. When colleagues leave frequently, the emotional weight of the job increases for those who remain. Caseloads grow, relationships get disrupted, and care quality can suffer. A recent study in acute hospitals found that a rise in nurse turnover correlated with significantly higher mortality rates, reminding us just how crucial staffing stability can be to the outcomes of people in support.

And then there’s the financial cost. Recruiting and onboarding new staff is expensive. When it becomes a constant cycle, those costs add up quickly, without solving the underlying issues driving people to leave.

So, Why Are Nurses Leaving?

The reasons nurses give for leaving aren’t new, but they are persistent.

Many cite stress, and emotional exhaustion, particularly in high-demand areas like mental health. A 2024 review found a strong correlation between UK nurses intending to leave their jobs and the criteria for mental health diagnoses including depression, PTSD, anxiety and burnout.

Younger staff, especially those early in their careers, are also reporting higher levels of dissatisfaction. A recent Guardian report revealed that over half of NHS staff aged 21–30 feel emotionally drained by their work, and more than one in five are unhappy with their pay.

Other common reasons include:

Feeling undervalued or underappreciated

Limited opportunities for career progression

Inflexible working conditions

Pay concerns

A lack of psychological support

In many cases, nurses aren’t leaving because they’ve stopped caring. They’re leaving because they feel like the system hasn’t cared enough for them.

What Actually Works When It Comes to Retention?

Fortunately, we’re not starting from scratch. There are several approaches that have shown promise, some of them already being introduced into healthcare settings.

1. Support Staff Well-being

Providing access to counselling, peer support, and regular debriefing sessions can make a real difference in reducing burnout. Structured support systems, such as Schwartz Rounds, give staff space to process the emotional side of their work.

2. Offer Flexibility

Flexible scheduling, part-time roles, and remote work options - where possible - help staff balance their professional and personal lives. Especially in mental health and social care, where emotional labour is high, flexibility can be a lifeline.

3. Invest in Development

Ongoing professional development, clear career pathways, and support for specialisation keep people engaged in their roles. When staff can see a future in their organisation, they’re far more likely to stay.

4. Recognise and Reward

Recognition doesn’t always have to be financial but feeling appreciated matters. Equal pay and bonuses help, but so do simple acts like celebrating achievements and listening to staff input.

5. Listen and Act

Gathering staff feedback is important, but acting on it is what counts. When teams feel heard, trust grows. When changes follow, retention improves.

Some NHS Trusts are already experimenting with coaching programmes, mentorship schemes, and retention bonuses for long-standing staff. While more evaluation is needed, early results are encouraging.

When Staff Stay, Everyone Wins

A workplace that supports and keeps its staff becomes more attractive to new recruits. Stability cultivates positivity. It improves care quality. And it builds team cultures that people want to be part of.

If we focus only on recruitment, we risk pouring water into a leaking bucket. But by building supportive, flexible, and values-driven workplaces, we stand a much better chance of holding onto the skilled, compassionate professionals already in the system.

The staffing crisis in mental health and social care isn’t going away overnight. But tackling it through retention by supporting the people we already have is the right way to initiate change.

By keeping skilled staff in post, we protect care quality, reduce costs, and build happier, more resilient services. Recruitment may fill gaps, but retention builds foundations.

At Northern Healthcare, we know that our people are at the heart of everything we do. That’s why we’re committed to creating a workplace where staff feel supported, heard, and genuinely valued. It’s time the sector gave both recruitment and retention the attention they deserve. And it starts with looking after those who are already making a difference.
