In the UK, employee turnover averages around 35% annually, over three times the generally accepted "healthy" rate of 10%. For small businesses and HR leaders, this level of attrition can be both disruptive and costly. With the average cost of replacing an employee ranging from £3,000 to £10,000 or more, high turnover eats into budgets and morale, slows productivity, and damages team cohesion.

Staff departures aren’t just about people leaving jobs. They represent lost knowledge, strained colleagues, delayed projects, and the invisible cost of culture erosion. More importantly, many of the root causes are preventable with the right systems and insights in place.

Macildowie partners with organisations to reduce turnover, align people strategy with business goals, and unlock recruitment ROI. This guide offers practical, evidence-based approaches to help HR leaders identify root causes of churn and take action to create workplaces where talent wants to stay.

Measuring and Diagnosing Turnover

Calculate Turnover Rate

Understanding your baseline turnover rate is essential. The formula is straightforward:

Turnover Rate = (Number of leavers / Average number of employees) x 100

Track this monthly and annually, separating voluntary and involuntary departures for clearer insight. For context, a 10–12% annual turnover rate is generally healthy. Anything higher signals a potential issue that needs investigation.

Break the data down by department, location, and tenure length. Are more people leaving within the first year? Do some managers or teams experience higher turnover than others? This segmentation helps you pinpoint areas that require closer attention.

Identify Root Causes

Once you know how many people are leaving, the next step is to understand why. Start with structured exit interviews. These should be conducted by someone other than the departing employee’s direct manager to encourage honesty. Third-party or anonymous systems can improve completion rates and provide more candid feedback.

Use surveys, 1:1 stay interviews, and employee listening tools to collect insight from current staff. Often, warning signs emerge long before people resign. Trends such as poor manager relationships, lack of career progression, or feeling undervalued commonly surface as reasons for turnover.

Core Strategies to Reduce Turnover

Strategic Hiring & Expectation Setting

Retention starts at recruitment. Hiring individuals who align with your company values and setting accurate expectations from day one can significantly reduce early attrition.

Ensure job descriptions reflect the actual day-to-day experience and culture. Use realistic job previews and involve team members in the selection process. The goal is to reduce mismatch between what candidates expect and what they encounter.

Competitive Pay & Compensation Review

Money isn’t everything, but it matters. Periodic benchmarking of salaries against local and industry standards is essential. If your pay is significantly below average, even the most engaged employee may be tempted by a better offer elsewhere.

However, non-financial rewards also carry weight. Performance bonuses, wellbeing stipends, flexible work arrangements, and cost-effective perks like birthday leave or employee discounts enhance your offer without ballooning the payroll budget.

Onboarding & Early Engagement

First impressions last. Up to 90% of new hires decide within the first six months whether to stay. A structured onboarding programme can boost one-year retention by 25% or more.

Effective onboarding includes role clarity, early wins, cultural immersion, and a buddy system. Weekly check-ins during the first month, followed by 30/60/90-day feedback sessions, help new hires feel welcomed and supported.

Career Development & Internal Mobility

A lack of growth opportunities is one of the top reasons employees leave. Organisations that provide training, mentoring, and visible career paths can significantly reduce turnover.

Introduce personalised development plans, skill-building workshops, and internal job boards. Promote a culture where growth doesn’t always mean upward movement; lateral moves and special projects also count.

Employees who see a future within the business are more likely to stay. Regular career conversations and transparent promotion criteria show your commitment to their success.

Recognition & Wellbeing Programmes

People need to feel valued. A recognition-rich culture, where good work is regularly acknowledged, is linked to up to 31% lower turnover rates.

Praise should be timely, specific, and genuine. It can be public or private, informal or formal. Recognition tools, peer-nomination schemes, or leadership shoutouts all help reinforce positive behaviours.

Couple this with wellness support: EAPs, mental health days, physical health incentives, and stress management tools. A healthy, appreciated workforce is more likely to stay engaged and committed.

Manager Training & Culture Engagement

Poor management remains one of the most cited reasons for leaving a job. Leaders shape the daily experience of employees, and undertrained managers often unknowingly drive talent away.

Provide line managers with training in coaching, communication, and conflict resolution. Encourage feedback loops, where team members can safely express concerns.

Beyond individual relationships, company culture plays a critical role. Foster inclusion, transparency, and shared purpose. When employees connect with the culture, they feel they belong.

Tools & Quick-Win Checklist

Sometimes small, quick actions can yield significant results. Here’s a six-point checklist to kickstart retention improvement:

• Hire with clarity: Use structured interviews and ensure role expectations are aligned.
• Review pay and perks: Benchmark regularly and introduce low-cost rewards.
• Onboard thoroughly: Include cultural orientation and scheduled check-ins.
• Support development: Offer budgets or access to learning platforms.
• Recognise contributions: Use formal and informal recognition to boost morale.
• Train your managers: Equip leaders with tools to lead empathetically.

Set SMART goals: Reduce turnover by 20% within 12 months, increase internal mobility by 25%, and improve onboarding satisfaction scores to 85%+.
