Voluntary vs. involuntary attrition

There are plenty of reasons behind an employee leaving a company. These reasons can best be categorized as voluntary and involuntary.

Voluntary attrition

Voluntary attrition occurs when employees choose to leave the organization of their own accord. This may happen for the following reasons:

• Resigning to accept a job at another company
• Retiring
• Leaving to start a business
• Quitting to pursue further education
• Departing due to relocation

Voluntary attrition is important because it often reflects employee satisfaction, company culture, and competitiveness in the job market. High voluntary attrition rates may indicate issues with employee engagement, career growth opportunities, employee compensation and benefits, or work-life balance.

HR plays a critical role in addressing the reasons for potential employee departure and providing solutions—especially to top talent—to prevent resignations.

Involuntary attrition

Involuntary attrition happens when the organization initiates the employee's departure. It may happen for several reasons:

• Layoffs due to economic downturn
• Terminations for poor performance
• Dismissals for policy violations
• Job eliminations due to restructuring
• Contract non-renewals

Involuntary attrition is significant because it often reflects company's financial health, workplace culture, performance management effectiveness, or compliance with company policies and legal requirements.

Both types of attrition significantly impact an organization's operations, culture, and bottom line. This is why it’s critical for companies to understand and manage both voluntary and involuntary attrition to gain better control of their workforce dynamics and create more stable, productive work environments.

What factors typically lead to attrition?

Attrition occurs due to various factors, some within and others beyond the control of employees or employers. Recognizing these factors allows organizations to develop targeted retention strategies and create a work environment that encourages long-term commitment.

Here are some common scenarios that may lead to attrition:

1. A hostile work environment characterized by poor teamwork and inadequate support from leadership can drive employees to seek opportunities elsewhere.
2. Employees may leave if they feel their career growth is stagnating, lacking the necessary resources and guidance for advancement.
3. Challenges in managing professional and personal responsibilities and maintaining a healthy work-life balance can lead to burnout and eventual departure.
4. Inadequate or uncompetitive pay and benefits packages may cause employees to seek better offers.
5. Structural shifts, mergers, or acquisitions can result in job eliminations or cultural misalignment, leading to both voluntary and involuntary departures.
6. Employees may be terminated for breaching company policies or engaging in inappropriate behavior.
7. Consistent underperformance may result in involuntary termination.
8. Personal reasons, such as life events like relocation, family responsibilities, or the pursuit of education, can prompt voluntary departures.
9. Employees may leave if they feel their values or working styles don't align with the organization's culture.
10. A lack of clear career paths or promotion opportunities within the organization can drive ambitious employees to look elsewhere.

Calculating your attrition rate

The attrition rate measures the percentage of employees who leave a company over a specific period, typically a year. It's a key metric for assessing employee retention and overall workforce stability.

The formula to calculate your annual attrition rate is:

Attrition rate = (Number of employees who left / Average number of employees) x 100

Here are the exact steps to calculate it:

1. Calculate the average number of employees:
• Add the number of employees at the beginning of the year to the number of employees at the end of the year.
• Divide the number you get by 2 to get the average.
2. Count the number of employees who left:
• This includes all employees who resigned, were terminated, or retired during the year.
3. Apply the formula:
• Divide the number of employees who left by the average number of employees.
• Multiply the result by 100 to get the attrition rate as a percentage.

Here’s an example:

• Beginning of the year: 200 employees
• End of the year: 220 employees
• Number of employees who left: 30
• Average number of employees: (200 + 220) / 2 = 210
• Attrition rate: (30 / 210) * 100 = 14.29%

What's a healthy attrition rate?

A healthy attrition rate ranges from 10% to 15% yearly. Among companies that provide professional services, the average attrition rate in 2023 was 12.5%. Working within this percentage allows companies to maintain a stable workforce despite natural employee movements through resignations and retirements.

Low attrition may indicate fewer job opportunities in the market, while high attrition rates reflect a lack of job satisfaction.

How does attrition affect a business?

A high rate of attrition can significantly impact an organization in several ways:

Financial impact

A company may experience increased recruiting costs because it will need to replace departing employees. Consequently, it will often mean higher training expenses for new hires and potential loss of revenue due to decreased productivity during transition periods.

It’s also a possibility that you will need to offer higher salaries as a way to attract and retain talent in a competitive market.

Productivity

The loss of experienced employees leads to knowledge gaps in your team, and the time you spend onboarding new employees will likely reduce overall productivity.

This causes disruptions in workflows and project timelines, leading to a potential decline in product or service quality during transition periods.

Company culture and morale

Frequent departures can create an atmosphere of uncertainty, negatively impacting the employees who stay, as they may experience increased workload, stress, and burnout.

Loss of team cohesion and working relationships that employees spend significant time building may also cause potential decrease in employee engagement and loyalty. Or even create a "domino effect" where departures inspire others to leave.

Leadership and succession planning

High attrition also represents a challenge for HR teams—in developing a strong leadership pipeline and implementing long-term strategic plans.

Frequent departures at various levels of the organization can disrupt the grooming of potential leaders, making it difficult to fill key positions from within and maintain organizational continuity.

How can companies reduce attrition?

While some attrition is unavoidable, companies can often retain valuable employees by implementing strategic practices.

Here's what businesses can do to reduce their attrition rate. 

Improve employee engagement

Companies can minimize employee attrition by improving employee engagement. When employees feel seen and valued, they are more likely to feel aligned with the company's mission and ready to work hard on shared goals.

What you can do:

• Implement regular one-on-one meetings between managers and employees
• Conduct quarterly pulse surveys to assess employee satisfaction and act on feedback
• Create cross-functional teams for projects to improve and encourage collaboration
• Establish an employee recognition program that highlights your workers’ achievements

Offer fair and competitive compensation and benefits

Fair compensation and employee benefits lead to higher employee retention. When employees are compensated and rewarded based on their results, they are less likely to seek other job opportunities.

What you can do:

• Conduct annual market research to ensure salaries are competitive
• Implement a transparent pay structure with clear criteria for raises and bonuses
• Offer incentive compensation and flexible benefits packages that employees can customize to their needs
• Consider providing unique perks like remote work options or unlimited paid time off

Provide growth and development opportunities

Today's employees seek employers who will encourage and support their career development. When employees find an employer who supports their professional goals, they will be motivated to stay in the organization for a long time. 

What you can do:

• Create individual development plans for each employee
• Allocate a specific budget for external training and conference attendance
• Establish a mentorship program pairing junior employees with senior staff
• Offer internal job rotations to broaden employee skills and experience

Create a positive work environment 

A supportive work environment that recognizes and praises employees' results is setting itself up for long-term success, as evidenced by high retention rates. A company culture that promotes mutual respect and collaboration is a foundation for a work environment people would want to be, contributing to its success.

What you can do:

• Train managers in effective leadership and communication skills
• Promote work-life balance by discouraging after-hours work communications

• Implement a transparent conflict resolution process
• Regularly assess and improve workplace ergonomics and facilities (or offer work-from-home stipends to remote workers)

Attrition FAQs 

What's the difference between attrition and turnover?

Attrition and turnover are related concepts, but they have different scopes and calculations.

Attrition typically refers to the natural reduction in the workforce over time without necessarily replacing those who leave. Turnover includes both departures and new hires, measuring the rate at which employees are replaced.

Attrition is often viewed as a long-term trend that may be part of a company's strategy, whereas turnover is a broader measure of workforce fluidity that can indicate short-term fluctuations in staffing.

What is internal attrition?

Internal attrition happens when an employee leaves their current role to take on a different position within the same company rather than leaving the organization entirely.

While internal attrition doesn't result in a net loss of employees for the company, it can still impact team dynamics, productivity, and resource allocation within specific departments or projects.

What is natural attrition?

Natural attrition refers to the reduction in the workforce that occurs through unavoidable or expected reasons, such as retirement, relocation, or personal life changes, without the employer actively seeking to reduce staff numbers.

Can attrition ever be beneficial for an organization?

Attrition, when approached strategically, can benefit the company.

When low-performing employees or team members not aligned with a company's mission leave, they create space for new talent with innovative ideas and perspectives.

How does attrition affect recruitment strategies?

Attrition rates help companies build more effective recruitment strategies.

or instance, low attrition rates allow companies to focus on candidates qualified for specialized, strategic roles who can drive business growth rather than just filling the gaps.

On the other hand, high attrition rates ask organizations to reevaluate their recruitment process, focusing on candidates who better fit vacancies and are likely to stay with a company long term.  

How can exit interviews help in reducing attrition?

Exit interviews enable companies to understand the reasons behind employee departure.

Employees who leave the company can provide valuable insights into how the system works or where it needs improvements. Exit interviews can serve as guides for enhancing employee satisfaction and productivity, reducing attrition rates in the future.
