Predicting Employee Attrition: Analysis and Recommendations

Employee attrition poses significant challenges to organizations, affecting productivity, morale, and financial performance. High turnover rates can escalate recruitment costs, deplete institutional knowledge, and disrupt workflows. This case study explores the dynamics of employee attrition within an organization, identifying key contributing factors, and offer strategic recommendations to enhance employee retention.

The dataset provided by IBM encompasses data from three distinct departments, offering a comprehensive view of employee behavior, satisfaction, and organizational dynamics.

Business Use Cases

This analysis addresses three primary business objectives:

1. Predicting Individual Employee Attrition: Developing a model to identify employees at risk of leaving, enabling proactive intervention.
2. Depicting Important Factors for Employee Departure: Understanding the primary reasons behind employee turnover to address underlying issues.
3. Improving Employee Retention: Crafting data-driven recommendations to enhance satisfaction and reduce attrition rates.

Framing the Key Questions

To navigate the complexities of employee attrition, the following key questions guide our analysis:

Attrition Analysis

• What percentage of employees leave the company (overall attrition rate)?
• Are there patterns in who leaves (e.g., age, gender, job role, department)?

Satisfaction and Attrition

• How do satisfaction levels (job, environment, relationship) differ between employees who leave vs. those who stay?
• Is there a relationship between work-life balance and attrition?

Workplace and Compensation

• Are employees who leave paid significantly less than those who stay?
• Does overtime or business travel correlate with higher attrition?

Career Progression

• Do employees who leave have fewer years in their current role, fewer promotions, or less training?

Demographics and Attrition

• Does age, marital status, or education level influence attrition?

Predictive Insights

• Can we predict which employees are likely to leave based on their attributes?

Attrition Analysis

Overall Attrition Rate

Our analysis reveals that 16.1% of employees are leaving their positions, while 83.9% are staying. This overall attrition rate serves as a baseline for understanding the turnover landscape within the organization.

Attrition by Age

Age is a significant factor influencing employee turnover. Employees in their early 20s exhibit the highest attrition rates, nearing 50%. As age increases, the likelihood of leaving diminishes sharply, stabilizing between 10-20% for those in their mid-20s to 30s, and dropping below 10% for employees aged 50 and above.

Attrition by Gender

Attrition rates between males and females are relatively comparable, ranging between 15-20%. This parity suggests that gender is not a primary driver of employee turnover within the organization.

Attrition by Job Role

Different job roles exhibit varying attrition trends. Sales Representatives lead with the highest attrition rate at nearly 40%, followed by Healthcare Representatives at around 20%. In contrast, positions such as Managers, Research Directors, and Manufacturing Directors showcase the lowest turnover rates, all below 10%.

Attrition by Department

Departmental analysis reveals that the Human Resources and Sales departments share the highest attrition rates at approximately 20%, whereas Research & Development maintains a notably lower rate of around 10%.

Monthly Income Distribution by Attrition Status

Key Observations

The distribution of monthly income provides deeper insights into attrition trends:

• Overall Income Distribution:

  • A majority of employees, regardless of their attrition status, earn between 2,500 to 5,000 monthly.
  • There's a noticeable skew towards lower-income brackets, with fewer employees earning above 10,000.

• Employees Staying:

  • The 2,500 to 5,000 income range holds the highest frequency.
  • As income increases, the number of employees choosing to stay decreases steadily.
  • Employees earning above 10,000 show a lower propensity to leave, indicating that higher compensation correlates with increased retention.

• Employees Leaving:

  • A higher concentration exists in the 2,500 to 5,000 income bracket.
  • The likelihood of leaving diminishes sharply with rising income, with minimal turnover among those earning above 10,000.
  • This trend underscores a strong negative correlation between income and attrition.

Career Progression

Years in Current Role

Analyzing tenure reveals a clear distinction between those who stay and those who depart:

• Employees Leaving: On average, have 2.65 years in their current role.
• Employees Staying: Boast a longer tenure, averaging 4.48 years.

This disparity suggests that shorter tenure correlates with higher attrition rates.

Number of Promotions

Promotion frequency offers additional perspective:

• Employees Leaving: Average of 2.62 promotions.
• Employees Staying: Slightly higher at 2.90 promotions.

While the difference is modest, it hints that career progression opportunities may influence retention.

Training Times Last Year

Training engagement presents a subtle yet notable trend:

• Employees Leaving: Averaged 2.83 training sessions last year.
• Employees Staying: Slightly more at 2.94 training sessions.

The minimal variance suggests that while training is consistent, it may not be the primary driver of attrition.

Demographics and Attrition

Attrition by Average Age

Age dynamics play a pivotal role in employee retention:

• Employees Staying: Average age of 37.6 years.
• Employees Leaving: Younger average age at 33.6 years.

This indicates that younger employees are more susceptible to leaving the organization.

Attrition by Education Level

Educational attainment offers a nuanced view:

• Employees Staying: Average education level of 2.93.
• Employees Leaving: Slightly lower at 2.84.

This marginal difference suggests that education level has a limited impact on attrition rates.

Attrition by Marital Status

Marital status emerges as a significant determinant:

• Employees Staying:

  • Divorced: 35%
  • Married: 55%
  • Single: 10%

• Employees Leaving:

  • Divorced: 65%
  • Married: 45%
  • Single: 90%

The stark contrast, especially among single employees, underscores the influence of personal circumstances on employment decisions.

Unique Insights

Through meticulous analysis, several key insights have surfaced:

1. Younger Employees Have Higher Attrition Rates:

   • Employees in their early 20s exhibit attrition rates nearing 50%, a stark contrast to their older counterparts.
   • Attrition stabilizes post-mid-20s, dropping below 10% for those aged 50 and above.

2. Compensation is a Critical Factor:

   • Employees earning below 5,000 monthly are most likely to leave.
   • Higher income brackets correlate with reduced attrition, highlighting the importance of competitive compensation.

3. Sales and HR Roles are High-Risk:

   • Sales Representatives face a 40% attrition rate.
   • HR Department employees also exhibit elevated turnover at around 20%.
   • These roles may require targeted retention strategies.

4. Short Tenure and Limited Career Progression Correlate with Attrition:

   • Employees with fewer than 3 years in their current role and less than 3 promotions are more inclined to depart.
   • This suggests that opportunities for advancement play a role in retention.

5. Single Employees are at Higher Risk:

   • An overwhelming 90% of employees leaving are single, compared to 10% who are married or divorced.
   • Marital commitments may provide additional stability and reduce turnover likelihood.

6. Training Opportunities Matter:

   • Employees receiving fewer than 3 training sessions annually show a higher propensity to leave.
   • Continuous professional development is essential for employee satisfaction and retention.

7. Job Satisfaction Plays a Role:

   • Employees departing report lower job satisfaction compared to those who remain.
   • Enhancing job satisfaction can be a pivotal strategy in reducing attrition.
