Workforce Scheduling Optimization: How to Reduce Labor Costs Without Overstaffing or Burnout

Whether you manage a restaurant, a cleaning company, or a retail operation, poor scheduling can take a heavy toll on your business’s finances and reputation.

Workforce scheduling optimization helps organizations improve shift assignments, leading to cost savings, higher productivity, and better operational efficiency.

In this guide, we’ll explain what scheduling optimization means, explore the metrics you should track, and share tips you can use today.

What Is Workforce Optimization in Scheduling? 

Workforce optimization in scheduling means building employee schedules that balance coverage, cost, compliance, and fairness.

To do this, you need to account for the following:

• Demand (slow versus busy hours).
• Labor budget (how much you’ve got available to spend on your workforce).
• Employee skills (who can open, who can close, who’s certified to perform certain tasks or be at specific job sites, etc.).
• Availability and preferences (so your employees can and will show up consistently).
• Compliance and other labor rules (such as rest and break times, overtime regulations, and maximum consecutive hours/days worked).
• Business goals (like sales targets or customer service baselines).

Constraint programming is often used to balance these constraints and ensure fairness in workforce scheduling optimization, integrating employee preferences and legal requirements into the scheduling process.

A helpful way to think about workforce scheduling optimization is that it moves you from simply being staffed to truly being covered. Too many managers know the struggle of having enough employees on shift or site, but still running into issues because the skill mix is off, the strongest workers are scheduled elsewhere, and so on.

In practice, optimizing schedules means staggering breaks, using sales data to predict busy periods, or making sure every shift has the right mix of experience. A security company, for example, might match specialist guards to specific sites while distributing weekend shifts fairly across the team.

There are big benefits to this optimization: You’ll reclaim hours you’d otherwise spend on manual adjustments, and your labor costs will become more predictable; your employees will get more stable, fair schedules, which typically means lower turnover; and your customers will get better service because the right people are working at the right times.

Workforce scheduling optimization example

Picture this: Joe’s Diner, a mid-sized restaurant, has strong lunch and dinner rushes, but a dead zone between 2 pm and 5 pm. Right now, the business is facing several hurdles:

• The manager, Lisa, spends 10–12 hours per week building and fixing schedules by hand. Manual scheduling processes often lead to errors and inefficiencies, as Lisa is constantly adjusting when servers call out or a private event gets booked. Automating shift creation through workforce scheduling optimization could save the business significant time.
• Labor costs are high (36% of revenue) because afternoons are padded “just in case.”
• Staff stand around during the afternoon lull.
• Guests wait too long for tables during peak hours, so shifts run long, and overtime creeps in.

By optimizing workforce scheduling, Joe’s Diner can overcome these challenges. Here’s what the team does:

• Manager Lisa reviews 3 months of point-of-sale (POS) data and reservation information. She spots clear patterns: Friday and Saturday dinners run 50% higher than weekday evenings, Tuesday lunch is surprisingly strong due to a nearby office park, and the 2–5 pm window is consistently slow across weekdays.
• Lisa rebuilds the schedule so that dinner shifts get more servers on weekends, Tuesday lunch has extra team members, and most lunch staff clock out by 3 pm.
• Lisa sets 2 clear scheduling rules:

1. No “clopening shifts” (closing one night, then opening the next day).
2. Anyone approaching overtime needs manager approval before picking up extra shifts.

Over a few months, Joe’s Diner will likely see a drop in labor costs, time spent on scheduling, and turnover, due to more predictable, fairly distributed shifts.

In the real world, Meera Watts, founder and CEO of Siddhi Yoga International, experienced a similar breakthrough.

The problem: “At Siddhi Yoga, we had reached a stage where our number of instructors had increased rapidly, but our time management system had not kept up. We were constructing blocks of classes on the basis of weekly hours as opposed to the real student attendance pattern. Therefore, on some mornings we had three certified instructors on the floor, which pulled in less than eight students, and on our fullest demand weekend slots, we were operating lean with instructors already exhausted by back-to-back lessons earlier in the week.”

The solution: “We extracted three months of enrollment data and completely reconstructed our instructor blocks around the actual arrival of students. The results were dramatic…The number of idle scheduling gaps decreased by approximately 30% during the first quarter of our restructuring. More to the point, complaints on instructor fatigue decreased as well, and student satisfaction rates in our post-class surveys increased significantly in 60 days.”

Metrics That Can Help You Optimize Your Workforce Schedules 

To have the same success as Joe’s Diner and Siddhi Yoga International, there are some vital signs to track. These workforce optimization metrics give you visibility into how your schedules are performing and where you can improve.

Labor cost percentage

Most service businesses aim for a labor cost percentage of 25–35%, but your industry benchmark may differ. No matter what industry you’re in, if you’re running at 40%, it’s a clear signal that something is wrong. Review this weekly and adjust staffing during slow periods or high-overtime shifts before costs get out of control.

Labor cost percentage = total labor costs (wages + benefits + payroll taxes) in 1 period ÷ gross revenue in the same period

For example, say you run a mid-sized restaurant with $20,000 in gross revenue last week. Your total labor costs, including payroll taxes, come out to $7,000. When you plug that into the formula, you get 35%, which is the top of the healthy range.

If you can, add some items to your offering that don’t cost much to make. If you’re running a restaurant, for instance, you might want to add seasonal drinks or bread baskets with flavored butter to your menus. That’s a good way to upsell to customers and lower average costs.

There are other strategies you can use to lower this number, depending on your business type. 

“When we began tracking the difference between planned and actual hours, we discovered that approximately 8-10% of time was lost due to inefficient routing,” said Khrystyna Boiko, business assistant at Wow Now Cleaning. “After adjusting schedules and assigning teams to zones, we reduced excess hours and reduced labor costs by approximately 12% over the quarter.”

Schedule accuracy

Schedule accuracy is a measure of how well you’ve forecasted your labor needs. Here’s the formula:

Schedule accuracy (%) = (Scheduled hours ÷ actual hours worked) × 100

For example, if you planned for 100 hours but your team worked 115 due to overtime, call-ins, and extensions, your accuracy is 87%: (100 ÷ 115) × 100 = 86.95%, rounded to 87%.

While there are no accepted industry benchmarks, anything under 85% is generally considered low, while anything above 95% is excellent. Low accuracy usually means your forecast is off (maybe hours are placed in the wrong times), you’re understaffed (so shifts often run long or the schedule needs regular adjustments), or your change process is messy (e.g., coverage is handled late). 

For instance, a cleaning company may have low accuracy because Friday schedules are always off, as client cancellations don’t reach workers in time. Regularly reviewing schedule accuracy (sometimes called schedule adherence) helps you catch issues early. 

Katie Breaker, sales director at BirdieBall Golf, told us her approach:

“I will always examine first schedule adherence, as that will inform you whether your plan did not die in the middle of the week, or just looked nice on Monday morning. When your team is continually going off schedule, it is a demand forecasting issue, but not a people issue. Following up on compliance after a week allowed us to identify the areas that were understaffed on our busiest windows before it could even reach our number.”

Absenteeism rate

The absenteeism rate measures the relationship between unplanned absences and scheduled hours. Note that this metric doesn’t include planned vacations or family leave, as it’s supposed to capture last-minute cancellations.

Absenteeism rate (%) = (Unplanned absence hours ÷ scheduled hours) × 100

For instance, if you’ve scheduled 400 hours and there are 25 unplanned absence hours, your absenteeism rate is 6.25%. That would be a problem. According to the Bureau of Labor Statistics,  restaurants typically have an absenteeism rate of around 3–4%.

If you’re above 4%, your staff may be experiencing burnout due to unpredictable schedules, a poor work-life fit, or low engagement. “A pattern there is generally an indication that your schedule is wearing people down before you even realize it,” said Watts.

For instance, a warehouse running at 8% absenteeism might discover that back-to-back closing and opening shifts are the culprit. Fixing root causes, like ensuring staff get enough rest time between shifts, can quickly bring absenteeism back to a healthy range.

That being said, when absenteeism is confined to a few individuals, it may not be due to your schedules. Having a 1:1 with the person(s) in question and asking them to train their replacement so someone can fill in when they’re absent may solve the issue.

Overtime hours

To get overtime hours, track time worked beyond your standard thresholds (typically 40 hours per week or 8 hours per day, depending on your jurisdiction). Some overtime is unavoidable, so if you find that overtime premiums amount to less than 5% of your total wages, you might have little to worry about. 

However, if you’re often well above 5%, you’re likely either understaffed or your schedules need work. If you’re paying 15% of wages (or more) as an overtime premium, you might save money and reduce employee burnout by hiring another part-time employee.

Overtime eats into your margins and burns out employees. Reddit is full of employees venting about how overtime requests put them in a tough spot. 

Employee utilization rate

Employee utilization tells you how much of your employees’ time is spent on productive tasks. 

Employee utilization rate (%) = (Productive time ÷ paid time) × 100 

For example, if your hotel housekeeping staff clocks in for 8 hours but rooms only need 6 hours of work, your utilization rate is 75%.

Low utilization means you’re overstaffed during slow periods, but utilization above 90% often leads to burnout and quality problems. You want some slack for breaks and unexpected tasks, and a sustainable pace, so a utilization rate of 80–85% is desirable.

Shift fill rate

When you post open shifts, what percentage actually gets claimed? The shift fill rate tells you how often your open shifts are taken, which also gives you insight into how attractive they are. Here’s the formula:

Shift fill rate (%) = (Claimed open shifts ÷ posted open shifts) × 100

For example, if you run a cleaning company and put up 20 shifts and only 12 get taken, your fill rate is 60%, and you’re probably going to be scrambling to cover the rest. Low fill rates often mean the shifts are unattractive, you’re not giving enough notice, or there’s a mismatch between available hours and your team’s preferences. 

You might need shift premiums for hard-to-fill times or alternative work schedules that better match your workforce.

7 Workforce Optimization Tips 

Here are 7 workforce optimization tips you can put into practice today to balance employee and business needs when creating schedules.

Use historical data to balance staffing levels

Instead of guessing, pull 8-12 weeks of sales data, foot traffic, or call volumes and look for patterns by day, time, and season. A retail store might discover that the first week of each month runs 25% hotter due to paycheck timing. 

Build your base schedule around the data, then adjust as new information comes in.

Balance cost efficiency with employee satisfaction

The cheapest schedule often creates bigger problems later. Burnout, turnover, and poor service usually cost more than the labor you saved.

Look for patterns in complaints, shift swaps, and absenteeism. These usually point to deeper scheduling issues, not isolated problems.

A strong schedule balances efficiency with predictability. That means giving employees some control over their hours, avoiding erratic shifts, and distributing desirable shifts fairly. When schedules feel stable and fair, engagement improves and callouts drop.

Implement rule-based scheduling constraints

Define the rules your schedules must follow, then build systems that enforce them for you automatically.

If you’re using Excel to make a work schedule, you can start building rule-based templates that include minimum rest time between shifts, maximum consecutive days worked, required certifications for specific roles, or overtime thresholds that trigger approval.

Human resources expertise is essential in setting up compliant scheduling systems that align with organizational policies and labor regulations.

For instance, a healthcare facility might require every shift to include at least one RN with cardiac certification.

Did You Know?

Connecteam lets you set scheduling rules so you have an automated system that respects employee needs and regulatory mandates. Using scheduling software can also help ensure compliance with local, state, and federal labor laws by tracking regulatory changes and setting up alarm triggers for potential violations. No spreadsheet needed.

Build forecasting into your scheduling process

Great schedules anticipate demand. Start with your historical baseline, then add or subtract shifts based on what you know is coming: promotions, local events, weather, seasonal trends. 

A lawn care company knows spring means a surge in demand, much as a ski resort staffs up for holiday weekends. The more accurately you predict demand, the more precisely you can staff. 

Create skills-based schedule templates

Note each team member’s skills, certifications, and experience levels. When building your schedules, focus on leveraging your team’s talent and optimizing assignments to maximize operational efficiency.

Be sure to match each shift’s needs with your team members’ skills to ensure you have the right coverage.

Advanced AI tools can analyze millions of possible combinations of skills, locations, and time slots to create optimal workforce schedules, improving operational efficiency.

“Shift assignment is [working] on a calendar and putting names on it, and scheduling goes much further. It implies matching the right skill sets for the right tasks at the right time for work to keep progressing without gaps and wasted hours,” said Johannes Hock, president of Artificial Grass Pros.

“At Artificial Grass Pros, we run multiple installations at once. If I assign shifts without taking into account project stage, ground conditions, or otherwise crew experience, jobs stall.”

Skills-based scheduling prevents situations where you’re technically staffed but practically short-handed.

If you’re struggling to keep up with your team’s skills on a spreadsheet, try Connecteam for automating skills-based scheduling. All you do is enter your team’s skills and specify the needs for each shift, and the app takes care of the rest.

Let your employees self-serve their schedules

To reduce your workload while giving employees more control, give your team workforce optimization tools to manage their own availability, request time off, swap shifts with qualified coworkers, and pick up open hours.

Self-service scheduling helps keep the team happy by giving them more control and flexibility, which boosts satisfaction and fairness.

When someone can swap a Saturday shift directly with a coworker (pending your approval), it gets handled in minutes instead of landing on your desk.

Scheduling apps like Connecteam offer self-service features that keep you in the loop without making you handle every request. Automated notifications can be sent to all employees when schedules are posted, reducing chaos in communicating and coordinating schedule changes.

Continuously improve your scheduling

Workforce scheduling optimization isn’t a problem you solve once and for all. Workforce management systems, powered by advanced computational capabilities, enable ongoing optimization by providing real-time data and integration with other enterprise platforms. Set a regular rhythm for reviewing your metrics and identifying opportunities for improvement—usually, it makes sense to do this once per month.

Effective workforce scheduling optimization requires assessing inefficiencies in your current staffing approaches, gathering data on past sales and customer demand, and routinely adjusting schedules to meet changing needs. Implementing flexible scheduling alternatives also enhances work-life balance and employee engagement.

What worked last month? What didn’t? Are certain shifts still hard to fill? Is absenteeism trending up or down? Use what you learn to change your approach. Small improvements grow over time into real gains in efficiency, cost control, and team satisfaction.

FAQs

What is workforce scheduling optimization? 

It’s the process of building schedules that balance efficiency, labor costs, compliance, and employee satisfaction. You use data, defined rules, and workforce optimization software to create schedules that meet your business needs.

What are the three components of workforce scheduling? 

The three core pieces are demand forecasting (predicting how much staffing you’ll need), schedule creation (assigning people to shifts based on skills, availability, and rules), and real-time management (handling same-day changes, absences, and unexpected demand).

How can I measure scheduling effectiveness? 

Track metrics like labor cost percentage, schedule accuracy, absenteeism rate, overtime hours, utilization, and shift fill rate. Comparing these over time shows whether your optimization efforts are paying off and where you still have work to do.
