What is Absence Rate?

Absence rate is a metric that calculates the percentage of scheduled work time that employees are absent. It's used to gauge workforce reliability, identify potential productivity issues, and measure the effectiveness of your absence management and absenteeism policy .

For multi-location businesses with hourly staff, the absence rate is a critical KPI. A 5% absence rate means that, on average, 1 out of every 20 scheduled shifts goes unfilled, creating constant staffing gaps, increased overtime costs, and service quality problems.

How to Calculate Absence Rate

The standard formula for calculating absence rate is:

Absence Rate = (Number of days/hours absent ÷ Total number of scheduled days/hours) × 100

Example Calculation for a Single Employee

An employee is scheduled to work 20 shifts (8 hours each = 160 hours total) in a month. They call out sick for 2 shifts (16 hours).

Absence Rate = (16 ÷ 160) × 100 = 10%

This employee has a 10% absence rate, meaning they miss 1 out of every 10 scheduled shifts.

Example Calculation for a Location

Your restaurant has 15 employees scheduled for 22 days/month at 7 hours/day. One employee is absent for 5 days during the month.

Total scheduled hours for the employee: 22 days × 7 hours = 154 hours
Absent hours: 5 days × 7 hours = 35 hours
Individual absence rate: (35 ÷ 154) × 100 = 22.7%

To calculate the location-wide absence rate:
Total scheduled hours (all employees): 15 employees × 154 hours = 2,310 hours
Total absent hours: 35 hours
Location absence rate: (35 ÷ 2,310) × 100 = 1.5%

Alternative Calculation Method

Some businesses calculate absence rate based on the number of absence occurrences rather than hours:

Absence Rate = (Number of absence occurrences ÷ Number of scheduled shifts) × 100

This method treats a 1-hour early departure the same as a full 8-hour shift absence, which may not accurately reflect the operational impact.

What's a "Good" Absence Rate?

Industry benchmarks vary, but for restaurants and retail:

Tumbleweed Southwest Grill, a 38-unit casual dining chain, reported an absence rate of about 3.5%, split evenly between absent and tardy employees. They considered this acceptable but worked to improve it through consistent policies.

Context matters. A 3% absence rate might be acceptable for a grocery store with deep staffing, but catastrophic for a small restaurant operating with minimal crews.

Why Absence Rate Matters

1. Operational Planning

Knowing your typical absence rate lets you staff appropriately. If your historical rate is 4%, you should schedule 104 hours to reliably cover 100 hours of operational needs.

2. Cost Management

Each percentage point of absence rate translates directly to increased overtime costs, emergency staffing expenses, and lost revenue from reduced service quality.

Example: 20 employees × 160 hours/month × $15/hour = $48,000 in monthly payroll. A 5% absence rate means 800 hours (50 shifts) monthly are unfilled. If you're paying 1.5× overtime to cover half of those, that's an extra $4,500/month in overtime costs alone.

3. Pattern Identification

Tracking absence rate by:

4. Legal Compliance

Under FMLA, ADA, and other laws, you must track employee absences to determine eligibility for protected leave. Absence rate data provides the foundation for these calculations.

5. Benchmarking and Improvement

You can't improve what you don't measure. Establishing baseline absence rates lets you test interventions (new scheduling practices, attendance incentives, policy changes) and measure their effectiveness.

Common Causes of High Absence Rates

Research identifies several primary drivers:

Health-related:

Work environment:

Personal circumstances:

Policy and cultural factors:

Strategies to Reduce Absence Rate

Strategy #1: Address Root Causes

Some good strategies restaurant managers can use include communication, consistent enforcement of policies, and creating a positive work environment. Simply punishing absences without understanding causes won't work.

Action: Conduct stay interviews. Ask reliable employees: "What would cause you to start calling out more frequently?" Ask departing employees: "Did anything about scheduling or work conditions contribute to your decision to leave?"

Strategy #2: Implement Flexible Scheduling

Flexible working hours and well-thought-out shift rotations can give employees greater job satisfaction and reduce absences.

When employees have some control over their schedules, they're less likely to call out for personal appointments or commitments.

Strategy #3: Provide Adequate Paid Leave

Employees without sufficient sick leave come to work contagious (spreading illness to coworkers and customers) or lie about why they're absent (claiming illness for personal needs). Adequate leave policies could reduce dishonest absences and address presenteeism, where sick employee attendance may hurt the business.

Strategy #4: Use Progressive Discipline Consistently

Clear consequences, fairly applied, reduce abuse. But discipline alone won't fix systemic issues.

Strategy #5: Recognize and Reward Good Attendance

Companies offer incentives such as preferred shift selection, small bonuses, or recognition awards for employees with excellent attendance records.

Strategy #6: Cross-Train Employees

When employees can work multiple positions, absence on one shift can be covered by someone already scheduled. This reduces the operational crisis caused by each absence.

Strategy #7: Leverage Technology

Manual absence tracking is error-prone and time-consuming. Modern tools like Breakroom automatically calculate absence rates by employee, location, shift, and time period. Armed with this data, it is much easier to identify problems and measure improvement.

Measuring Absence Rate: Best Practices

1. Define what counts as an absence: Do you count tardiness? Early departures? Partial days? Be consistent.

2. Exclude protected absences from disciplinary metrics: Medical leave, maternity or paternity leave, bereavement leave, and military leave shouldn't count against an employee in your absence rate calculations for discipline purposes. However, include them in operational absence rates for staffing planning.

3. Track both frequency and duration: An employee who calls out once for 5 consecutive days (likely serious illness) is different from an employee who calls out 5 separate times (possible abuse).

4. Set appropriate rolling windows: A 30-day window may miss patterns. A 12-month window may be too long. Most businesses use 60-90 day rolling periods for absence rate calculations.

5. Report and review regularly: 42.5% of restaurant chains execute absence management at the unit level and report to higher-level management. Regular reporting ensures problems don't go unnoticed.

Legal Considerations

When using absence rate data for discipline or termination:

1. Don't discriminate: Ensure absence rates and consequences don't disproportionately affect protected classes (race, gender, age, disability, religion).

2. Accommodate disabilities: Higher absence rates due to chronic conditions covered under ADA may require reasonable accommodation.

3. Respect FMLA: FMLA-protected absences cannot be counted against employees in attendance policies.

4. Follow state sick leave laws: Many states mandate paid sick leave and prohibit discipline for using it.
