Labour turnover measures how often employees leave a business and is a key indicator of workforce stability, HR effectiveness, and organisational cost control.
What is Labour Turnover?
Labour turnover refers to the rate at which employees leave an organisation over a set period of time. It includes resignations, retirements, dismissals, and redundancies, whether voluntary or involuntary.
It is typically measured as a percentage and provides insight into how attractive the workplace is to employees, how well staff are retained, and the degree to which the organisation needs to recruit and train new workers.
While some turnover is expected and can be healthy, allowing for the injection of new skills and ideas, excessive turnover can signal problems within the business and lead to significant disruption and cost increases.
Why Labour Turnover Matters
Labour turnover is used by human resource managers and senior leadership as a performance metric to gauge the health of the organisation’s workforce.
Key reasons it matters:
It helps evaluate the effectiveness of HR strategies, including hiring, training, and employee engagement.
It acts as an early warning system for morale and job satisfaction issues.
It impacts operational costs, especially in industries where onboarding and training are expensive.
It affects continuity and productivity, especially in roles requiring specialist skills or long ramp-up times.
For instance, in a customer service business, high turnover might mean that new, inexperienced staff are frequently interacting with customers, reducing service quality and customer satisfaction.
Calculating Labour Turnover
The Labour Turnover Formula
Labour turnover is calculated using the following formula:
Labour turnover (%) = (Number of employees leaving during the period ÷ Average number of employees during the period) × 100
Each part of the formula must be accurately determined:
Number of employees leaving during the period: This includes all leavers, regardless of whether the departure was voluntary or not.
Average number of employees: Usually calculated by adding the number of employees at the start and at the end of the period, then dividing by 2.
This calculation provides a percentage figure that can be used to compare against past performance or industry benchmarks.
Worked Example 1
A logistics company began the year with 180 employees and ended the year with 200 employees. Over the course of the year, 30 employees left the company.
Step 1: Calculate the average number employed
(180 + 200) ÷ 2 = 190
Step 2: Plug into the formula
(30 ÷ 190) × 100 = 15.79%
Interpretation:
This result means that around 15.8% of the workforce left during the year. For some industries, this might be acceptable. For others, it may be high.
Worked Example 2
A catering business had 40 employees throughout the year. Twelve employees left.
Labour turnover = (12 ÷ 40) × 100 = 30%
Interpretation:
A 30% turnover rate is high, particularly for a small business. The firm may need to investigate retention strategies and working conditions to improve workforce stability.
Causes of High Labour Turnover
Labour turnover, especially when it is consistently high, is often caused by a combination of internal and external factors.
Internal Causes
These are factors within the organisation’s control:
Poor working conditions: Unsanitary, unsafe, or uncomfortable environments can quickly drive employees away.
Low pay or limited benefits: If competitors offer better compensation, employees may leave for more attractive packages.
Lack of career development: Staff who feel they are not progressing may become demotivated and search for opportunities elsewhere.
Weak leadership: Ineffective or inconsistent management often leads to dissatisfaction and reduced loyalty.
Inflexible schedules: Inability to accommodate personal or family needs can push employees to leave.
Unclear job roles: Ambiguity in expectations can lead to frustration.
External Causes
These are factors generally outside the control of the business:
Competitive labour market: High demand for skilled workers can make it easy for employees to find better roles elsewhere.
Relocation: Employees may move for personal reasons, unrelated to job satisfaction.
Economic cycles: During times of economic growth, employees may take the opportunity to pursue new jobs or higher pay.
Recognising the difference between internal and external causes is crucial for effective HR responses.
Implications of High Labour Turnover
High labour turnover can create several serious challenges for an organisation. These can be financial, operational, and cultural.
1. Financial Implications
Recruitment costs: Advertising job roles, paying agency fees, conducting interviews, and managing onboarding take time and money.
Training costs: New employees often require formal training before becoming productive.
Lost productivity: It can take weeks or months before a new hire reaches full productivity. During this period, work may be slower or less efficient.
Temporary cover: Using temporary staff or paying existing employees overtime adds further expense.
If turnover is high, these costs accumulate quickly and erode profit margins.
2. Operational Disruption
Lower productivity: Frequent changes in staff interrupt workflow and require existing employees to take on extra duties.
Skills gaps: When experienced employees leave, their knowledge and expertise may not be easily replaced.
Increased errors: Inexperienced new staff are more prone to mistakes, especially in technical or regulated environments.
This can impact product or service quality and damage the firm’s reputation.
3. Recruitment and Retention Challenges
High turnover can damage an organisation’s employer brand, making it harder to attract skilled staff.
Remaining staff may feel overburdened or demoralised, leading to further resignations.
The recruitment cycle becomes constant, creating pressure on HR departments and line managers.
4. Cultural Consequences
Declining morale: Constant farewells and new faces can leave remaining staff feeling disconnected or unsupported.
Loss of team cohesion: Teams take time to bond and collaborate effectively. High turnover prevents this.
Weak leadership pipeline: It becomes harder to build up internal talent ready for promotion if experienced staff leave frequently.
Culture is difficult to quantify but critical to long-term organisational health. Persistent high turnover is almost always a red flag.
Implications of Low Labour Turnover
While high turnover is costly, excessively low turnover isn’t automatically a good thing. In some cases, it might signal other issues:
Stagnation: Without new hires, innovation and new ways of thinking may be limited.
Complacency: Long-serving employees may resist change or lose drive.
Lack of opportunities for promotion: If employees rarely leave, there may be few chances for others to advance, causing frustration.
Businesses need a balance between stability and renewal. A moderate turnover rate, appropriate to the industry, is usually ideal.
Interpretation Questions
Question 1
A medium-sized factory had 150 employees at the beginning of the year and 170 at the end. During the year, 20 staff left.
Step 1: Average number employed
(150 + 170) ÷ 2 = 160
Step 2: Labour turnover
(20 ÷ 160) × 100 = 12.5%
Discussion:
A 12.5% turnover rate may be acceptable for manufacturing, but the business should review trends over time and consider staff feedback to ensure it doesn’t worsen.
Question 2
A company’s turnover rate increased from 8% to 20% in two years.
What could this indicate?
Declining morale or dissatisfaction with recent organisational changes.
Increasing competition from other firms offering better pay or conditions.
Weaknesses in management or employee engagement.
A sign of instability, especially if many leavers are senior or experienced.
The HR team should investigate the underlying causes, such as via exit interviews or surveys.
Question 3
A hotel employs 100 people and experiences a 35% turnover rate.
Consequences might include:
Frequent training cycles and high recruitment costs.
Reduced service consistency, harming customer experience.
Disengagement among remaining staff.
Reducing turnover should be a key HR priority for the business.
Interpretation Practice – Scenario-Based Questions
Scenario A
Situation:
A software company has a 5% turnover rate.
Q: Should the business be concerned?
Answer:
This low turnover rate suggests good retention and employee satisfaction. However, if innovation is slow and the workforce is ageing, leadership should assess whether a lack of new perspectives might be limiting progress.
Scenario B
Situation:
A national retail chain reports 40% turnover in its store assistant roles.
Q: What are the implications and possible solutions?
Implications:
Disruption to customer service.
High recruitment and training cost.
Strain on managerial time and employee morale.
Solutions:
Increase pay or bonuses for store staff.
Provide clearer career progression paths.
Implement flexible working shifts.
Foster a more engaging working environment.
Developing Strong Interpretation Skills
When analysing labour turnover figures, students should:
Consider the context: Look beyond the number. Is it rising or falling? Has something changed recently?
Compare across industries: Acceptable turnover varies. Hospitality and retail may have higher natural rates than education or healthcare.
Examine staff levels: Is the turnover occurring mostly among junior or senior staff?
Use qualitative data: HR metrics should be paired with staff feedback, appraisals, and exit interviews for a complete picture.
A business decision made purely on numbers may be misleading if the underlying human factors are ignored.

FAQ
Seasonal businesses, such as those in retail or tourism, often employ temporary staff during peak periods and release them afterwards. This naturally inflates labour turnover figures. In these cases, high turnover is expected and not necessarily a sign of poor HR performance. Businesses should compare year-on-year data for the same periods and focus on core staff turnover rather than temporary roles. Analysing turnover separately for full-time and seasonal workers gives a clearer picture of long-term workforce stability.
Labour turnover varies widely between industries. For example, retail and hospitality often experience rates above 30%, due to the nature of low-pay and part-time roles. In contrast, professional services and public sector organisations typically aim for turnover rates between 5% and 15%. There is no fixed ‘normal’ rate, so businesses should benchmark against sector averages and their own historical data. A ‘normal’ rate also depends on business strategy—firms prioritising innovation may accept higher turnover to refresh talent regularly.
High turnover can have a significant impact on the morale of remaining employees. Constant departures may lead to increased workloads, uncertainty, and a lack of team cohesion. Employees may start questioning the reasons behind so many exits, which could spread dissatisfaction or fear. This creates a negative feedback loop, where low morale causes more resignations. Additionally, loyal staff may feel undervalued if they’re asked to train new colleagues repeatedly without recognition or incentive, further contributing to disengagement.
To uncover the root causes of turnover, businesses should implement structured exit interviews and anonymous staff satisfaction surveys. These tools provide qualitative insights into why employees choose to leave. HR departments can also track turnover by department, manager, or job role to detect patterns. High turnover in one area may point to management issues or unrealistic job expectations. Combining this with data on absenteeism, performance, and employee engagement helps form a detailed picture of underlying issues.
Yes, a short-term rise in labour turnover can sometimes be a by-product of positive change. For example, a business undergoing strategic transformation—such as restructuring, digitisation, or cultural shift—may see natural attrition as some employees decide the new direction no longer suits them. This turnover can open opportunities for fresh talent aligned with the business’s updated goals. However, it’s important for leadership to monitor whether key skills or experience are being lost and to ensure that change management is being handled effectively.
Practice Questions
Analyse the possible causes of a 25% labour turnover rate in a medium-sized manufacturing firm. (6 marks)
A 25% turnover rate may be caused by several internal factors such as poor working conditions, limited career progression, or low pay relative to competitors. If the firm does not invest in training or offers minimal employee benefits, staff may feel undervalued and seek better opportunities. External causes could include a growing local job market or regional economic recovery, making it easier for employees to find alternative work. Additionally, poor leadership or weak communication may lead to low morale. Identifying whether causes are internal or external is crucial for the firm to implement effective retention strategies.
Using a calculation, interpret whether a 12% labour turnover rate is likely to benefit a business that values innovation and regularly hires graduates. (9 marks)
Labour turnover = (Number of staff leaving ÷ Average number employed) × 100
If 18 staff leave from an average workforce of 150, the turnover is (18 ÷ 150) × 100 = 12%. For a business valuing innovation, this moderate rate may be positive, as it allows fresh talent and ideas to enter regularly. Graduate employees often seek rapid progression, so some turnover is expected. A 12% rate suggests enough stability to retain key staff while allowing natural change. However, if turnover rises or includes high performers, it could disrupt continuity. Regular review of staff satisfaction and exit reasons will help maintain an optimal balance for innovation and growth.
