HR Knowledge Base: Overtime Rules HR Teams Actually Get Asked (2026)

Why HR Needs a Knowledge Base, Not a Policy Page

Most overtime disputes I have watched unfold did not start with a bad policy. They started with a manager answering a question fast, in a hallway, with an answer that sounded reasonable and was wrong.

A policy document tells people what the company does. A knowledge base tells people what to say when someone asks. Those are different artifacts, and HR needs the second one more than the first.

This page is the structure I would use to build one. It is organized the way employees actually ask — by situation, not by statute — and each section ends with the answer you can safely give without escalating. For the deeper compliance workflow behind it, see the HR and payroll hub, and for employee-facing wording, the overtime FAQ answers for HR.

Article 1: Who Is Actually Eligible for Overtime

Start here, because roughly every other question depends on it.

Under the Fair Labor Standards Act, an employee is entitled to overtime unless they meet both parts of an exemption: a salary test and a duties test. Salary alone never exempts anyone. A job title never exempts anyone.

The duties tests that matter in practice:

• Executive. Primary duty is managing the business or a recognized department, regularly directs two or more full-time employees, and has real weight in hiring and firing decisions.
• Administrative. Primary duty is office or non-manual work directly related to management or general business operations, and includes the exercise of discretion and independent judgment on significant matters.
• Professional. Work requiring advanced knowledge in a field of science or learning, customarily acquired through prolonged specialized instruction.
• Outside sales. Customarily and regularly works away from the employer's place of business making sales.
• Computer employees. Specific systems analysis, programming, and design duties — not general IT support or help desk work.

The two misclassifications I see most often: an "assistant manager" who spends 90 percent of their shift doing the same hourly work as their team, and a salaried coordinator whose discretion is limited to following a checklist. Both are non-exempt no matter what the offer letter said.

What HR should say: exemption is decided by what the person does day to day, and HR reviews it, not the hiring manager.

Article 2: The Regular Rate Is Not the Hourly Rate

This is the single most expensive gap in HR knowledge, and it is invisible until an audit.

Overtime is 1.5 times the regular rate, which is total straight-time compensation for the workweek divided by total hours worked. Several forms of pay have to be folded in before you multiply:

| Pay type | In the regular rate? |

| --- | --- |

| Base hourly wage | Yes |

| Nondiscretionary bonus (attendance, production, safety) | Yes |

| Shift differential (night, weekend) | Yes |

| Commissions | Yes |

| On-call pay for restricted time | Yes |

| Discretionary gift bonus, no promise attached | No |

| Reimbursed business expenses | No |

| Paid time off hours not worked | No |

| Premium already paid at 1.5 for daily overtime | No, it is creditable |

A worker at 20 dollars an hour who earns a 200 dollar production bonus in a 50-hour week does not get 30 dollars of overtime. The bonus raises the regular rate, so the overtime premium rises with it. The overtime rate of pay guide walks the arithmetic; the overtime calculator does it for you.

Article 3: Hours Worked, Including the Hours Nobody Logged

Compensable time is not the same as scheduled time. Under the FLSA and the Portal-to-Portal Act, these are hours worked:

• Pre-shift setup, booting systems, donning required gear, security screening tied to the job.
• Post-shift closing, cleanup, cash reconciliation, handoff.
• Short rest breaks up to about 20 minutes.
• Interrupted meal periods where the employee was not fully relieved of duty.
• Answering calls, texts, tickets, or email outside scheduled hours.
• Required training and travel between worksites during the workday.

The rule HR has to internalize: if the employer knew or should have known the work happened, it is compensable — even if it was not approved. A policy that forbids unapproved overtime is enforceable through discipline. It is not a defense against paying for the hours.

What HR should say: report every hour you worked. If hours were not authorized, we will address the scheduling separately, but we will pay you.

Article 4: Approvals, Refusals, and Mandatory Overtime

Two questions arrive constantly and have counterintuitive answers.

Can we require overtime? For adult non-exempt employees, generally yes under federal law. There is no federal cap on weekly hours. Limits come from state law, union contracts, and sector rules — nurse mandatory-overtime restrictions in several states, one-day-rest-in-seven laws, and predictive scheduling ordinances in cities like Seattle, San Francisco, and New York.

Can we refuse to pay unapproved overtime? No. See Article 3.

The workable middle: require pre-approval, enforce it with coaching and documented discipline, and pay every recorded hour regardless. Any policy that trades one for the other is a liability.

Article 5: The Workweek Is Fixed and Seven Days Long

Overtime is calculated per workweek — a fixed, recurring 168-hour period the employer designates. It does not have to be Sunday to Saturday, but once set it cannot float to suppress overtime.

Consequences HR should have memorized:

• No averaging across weeks. 30 hours one week and 50 the next is 10 hours of overtime, not zero.
• No time-off substitution in private employment. Offering a day off next week instead of overtime pay is unlawful for private employers. Public agencies may use compensatory time under specific rules.
• Semi-monthly payroll still needs weekly math. The pay period is an accounting convenience; the workweek is the legal unit.

Article 6: Daily Overtime and State Overlays

Federal law is a floor. Where state law is more generous, the employee gets the better result.

• California — over 8 in a day at 1.5, over 12 at double time, seventh consecutive day rules. See the California calculator.
• Alaska, Nevada, Colorado — daily overtime thresholds of 8 or 12 hours with their own conditions.
• Colorado — also over 12 consecutive hours regardless of the daily total.
• Higher exempt salary floors — several states, including California, New York, and Washington, set salary thresholds above the federal minimum.

For multi-state teams, the rule is the work location, not the headquarters. Compare thresholds on the state overtime pages.

Article 7: Records, Retention, and Who Bears the Risk

Keep payroll records three years and time and earnings records two years under the FLSA. Many states require longer.

The reason this matters is evidentiary. In wage disputes, when the employer's records are incomplete, courts accept the employee's reasonable reconstruction of hours. Bad recordkeeping does not create neutral uncertainty — it shifts the outcome toward the employee. See the payroll records retention guide for the full schedule.

Building the Knowledge Base Your Team Will Actually Use

Four habits separate a knowledge base that works from a folder nobody opens:

• . One question per article, written in the employee's words. "Do I get overtime if I work through lunch," not "Meal period compensability."
• . A canonical answer plus an escalation line. Managers need to know both what to say and where the line is.
• . A dated review cycle. Salary thresholds, state minimum wages, and city ordinances change annually. Undated HR guidance ages into misinformation.
• . A calculator link in every money answer. People believe a number they can reproduce. Point them at the overtime calculator or the paycheck calculator.

Frequently Asked Questions

Does HR have to pay overtime that a manager did not approve?

Yes. If the employer knew or should have known the work was performed, the hours are compensable. Unapproved overtime is a performance and scheduling issue to be handled through coaching or discipline, not by withholding pay.

Can a salaried employee be entitled to overtime?

Yes. Salary is only one part of an exemption. Unless the employee also meets a duties test for an executive, administrative, professional, outside sales, or computer role, they are non-exempt and owed overtime regardless of being paid a salary.

Do bonuses change the overtime rate?

Nondiscretionary bonuses do. Attendance, production, safety, and similar promised bonuses must be included in the regular rate, which raises the overtime premium for the weeks the bonus covers. Truly discretionary gifts do not.

How long should HR keep overtime and timekeeping records?

The FLSA requires three years for payroll records and two years for the time and earnings records that support them. Several states require longer, so retain to the strictest applicable rule.

Can an employer give time off instead of overtime pay?

Private employers cannot substitute compensatory time off for overtime pay. Public agencies may use compensatory time under specific statutory conditions and prior agreement.

Does paid time off count toward the 40-hour overtime threshold?

Not under federal law, because overtime is based on hours actually worked. Some employers count PTO toward overtime by policy or contract, and that promise is enforceable. See does PTO count toward overtime.
