In HR, attrition refers to the gradual reduction of employees in a company when people leave, through resignation, retirement, or even internal transfers, and the company chooses not to refill those roles. It's a passive way the workforce shrinks over time.
Attrition is different from turnover. With turnover, companies actively hire to replace people who leave. But with attrition, those positions remain intentionally vacant, often to cut costs, streamline operations, or because the role is no longer needed.
Let’s say a senior sales manager retires after 15 years. Instead of hiring a new person for that role, the company distributes their work among the remaining team members. Over time, if several such roles go unfilled, the total headcount reduces. That’s attrition.
It’s a non-replacement approach to managing workforce changes, common in businesses undergoing restructuring, mergers, or digital transformation.
Here’s a simple formula to find the attrition rate:
Attrition rate (%) = (Number of employee exits ÷ Average number of employees) × 100
Example: If your company had 200 employees at the beginning of the year, and 30 left during the year, with an average workforce of 185:
Attrition rate = (30 ÷ 185) × 100 = 16.2%
This means 16.2% of your workforce exited without their roles being backfilled.
1. Inadequate compensation and benefits: When employees feel they’re not paid fairly or don’t see value in their benefits package, they begin exploring better-paying roles. Lack of pay transparency and minimal health or retirement benefits only worsen the situation.
2. No room for growth or development: Stagnation is a dealbreaker. Employees are more likely to leave when there’s no clear career path, little to no upskilling, or a lack of mentorship. If they can’t grow here, they’ll go elsewhere.
3. Burnout and poor work-life balance: Long hours, rigid schedules, and unrealistic workloads are major red flags. When employees are stretched too thin or don’t feel supported in managing their personal lives, attrition follows.
4. Ineffective leadership and poor management: Bad managers can make even great jobs unbearable. Micromanagement, poor communication, and lack of recognition can quickly demotivate employees, eroding trust and loyalty.
5. Toxic or misaligned company culture: If the culture doesn’t align with employee values, or worse, feels toxic or exclusionary, people leave. Culture drives belonging, and without it, engagement drops.
6. Lack of recognition and appreciation: It’s demoralising when hard work goes unnoticed. Employees who don’t feel valued are less likely to stay, even if the pay is competitive.
7. Poor working conditions: Uncomfortable workspaces, lack of tools or tech, or even unsafe environments can lead to higher attrition, especially in operational or field roles.
8. Business restructuring or mergers: When companies downsize, restructure, or merge, roles can be eliminated or changed. This often causes both involuntary exits and voluntary ones driven by uncertainty.
9. Personal reasons: Sometimes, attrition isn’t about the company at all. Health concerns, family responsibilities, relocation, or early retirement can lead employees to leave on their own terms.
10. Lack of challenge or purpose: Employees who feel bored, underutilised, or disconnected from their work are more likely to look for opportunities that offer intellectual or creative stimulation.
This happens when employees choose to leave on their own, often for better salary, career growth, improved work-life balance, or personal reasons. It’s one of the most common types, and also the most revealing. High voluntary attrition may signal dissatisfaction with company culture, compensation, or leadership.
Involuntary attrition is when the company decides to let employees go. This could be due to layoffs, performance-related terminations, or role redundancies. Unlike voluntary attrition, it’s often part of cost-cutting or restructuring efforts.
This is the kind of attrition that actually helps. When underperformers leave the organization, it creates room for stronger team dynamics and improved productivity. Functional attrition can be a sign that performance management systems are working.
The opposite of functional attrition, this occurs when top performers or critical team members leave, often due to burnout, poor management, or lack of growth opportunities. This type of attrition hurts morale, performance, and business continuity, and needs immediate HR intervention.
This refers to employees leaving due to retirement, long-term illness, disability, or death. It’s inevitable and often doesn’t reflect on company policies or culture. Still, HR must plan for succession and knowledge transfer in these cases.
When employees move to a different team or department within the same company, their previous role becomes vacant. While not a loss to the organization, it still qualifies as attrition and requires backfilling or restructuring to maintain continuity.
During mergers and acquisitions, attrition is common. Roles may become redundant, or employees may leave due to culture clashes or uncertainty. It’s essential to manage this period with transparent communication and retention strategies.
Some employees choose to exit the workforce before the traditional retirement age, sometimes with incentives offered by the employer. While this can be part of a cost-saving strategy, losing experienced talent early can impact institutional knowledge and mentorship pipelines.
Not always. Attrition isn't inherently negative, it depends on who’s leaving, why, and how often. For instance, when underperformers exit or employees move to new roles within the company, attrition can actually benefit the business by improving team performance or supporting internal growth. Even during restructuring, natural attrition can reduce workforce size without the need for layoffs.
However, when high performers or critical team members leave frequently (known as dysfunctional attrition), it can hurt morale, disrupt operations, and lead to higher rehiring costs. A consistently high attrition rate also signals deeper issues like poor leadership, lack of engagement, or toxic culture. So while some attrition is natural and even healthy, unmanaged attrition, especially when it affects top talent, can be damaging in the long run.
Though often used interchangeably, attrition and turnover mean different things in HR.
While attrition measures how many employees leave, retention tracks how many stay. HR teams aim to reduce attrition and boost retention, especially when it comes to high performers.
1. Go beyond basic exit interviews: Instead of just asking why someone’s leaving, ask what could’ve made them stay. Structured exit interviews, when paired with stay interviews, offer insight into manager dynamics, workload issues, and cultural mismatches. The goal? Spot patterns early and use that feedback to prevent future exits.
2. Keep compensation competitive: It’s not just about matching market salaries, it’s about offering total rewards. That includes health insurance, mental wellness benefits, performance-linked incentives, and work flexibility. HR teams should regularly benchmark compensation and benefits to avoid losing talent to slightly better packages elsewhere.
3. Offer real career growth opportunities: Employees who can’t see a clear growth path often seek one elsewhere. Transparent promotion frameworks, regular feedback loops, access to upskilling, and internal mobility opportunities can make all the difference. When people feel their careers are growing, they’re less likely to walk away.
4. Invest in culture and inclusion: People don’t leave jobs, they leave environments where they don’t feel heard, seen, or safe. Encourage open feedback, act on engagement survey results, and create an inclusive culture where everyone, across levels, identities, and locations, feels they belong.
5. Recognize and reward consistently: Regular appreciation, whether through peer-to-peer shoutouts or structured rewards, boosts morale and connection. Recognition isn’t just a feel-good perk, it’s a proven retention driver, especially for employees who go above and beyond behind the scenes.
6. Train managers to lead with empathy: Managers are one of the biggest drivers of attrition. HR must equip them with tools to manage conflict, give constructive feedback, and build psychologically safe teams. A well-supported manager can directly influence an employee’s decision to stay.
Employee attrition is a normal part of business life. But when left unchecked, it can damage culture, productivity, and even your employer brand. The key is understanding the causes and building a workplace where people want to stay and grow.
By tracking attrition rates, listening to your people, and investing in their growth and well-being, HR teams can turn a potential challenge into a strategic advantage.
Attrition means employees leave and their roles aren’t refilled. Turnover means employees leave and are replaced. Attrition reduces headcount; turnover doesn’t.
Use this formula: (Number of employee exits ÷ Average number of employees) × 100. It helps you track workforce shrinkage over time.
No. Some attrition is healthy, like when poor performers leave or during digital transitions. But losing top performers frequently (dysfunctional attrition) is harmful.
Declining morale, disengagement, lack of innovation, frequent resignations, and heavy rehiring costs are key warning signs.
