Time in Lieu

This is one practical reason many enterprise HR teams use time in lieu schemes primarily for salaried-exempt staff.

Time in Lieu Time in lieu (also called comp time) is paid time off granted instead of overtime pay for hours worked beyond the contracted schedule.

Time in lieu vs. overtime pay

For enterprise teams running high-volume or project-based workloads, time in lieu can reduce payroll costs significantly, but only if the accrual, approval, and expiry rules are documented and enforced consistently. According to the U.S. Bureau of Labor Statistics, overtime costs accounted for roughly 2.4% of total compensation for private-sector employees in 2024. Shifting eligible hours to comp time can recover a measurable portion of that spend.

Who is eligible for time in lieu?

Eligibility depends on three factors: jurisdiction, employment classification, and the employment contract.

Jurisdiction. In the United States, the Fair Labor Standards Act (FLSA) generally prohibits private-sector employers from offering comp time in place of overtime pay for non-exempt employees. Public-sector employers have broader latitude: state and local government employees can accrue comp time at 1.5 hours per overtime hour worked, up to statutory caps (240 hours for most roles, 480 hours for public safety). Private employers in the UK, Australia, Canada, and most of Europe operate under different frameworks; many allow time in lieu for all employees as long as average pay does not fall below the minimum wage threshold over the reference period.

Employment classification. In the U.S., exempt employees (those meeting FLSA salary and duties tests) are not entitled to overtime pay and can be offered comp time at the employer’s discretion. This is one practical reason many enterprise HR teams use time in lieu schemes primarily for salaried-exempt staff.

Contract terms. Even where lawful, time in lieu must be agreed in writing: either in the employment contract, a collective bargaining agreement, or a standalone comp time policy. Verbal agreements expose employers to wage theft claims if an employee later disputes whether the arrangement existed.

How time in lieu accrual works

Accrual rules vary by policy, but the most common structures are:

Hour-for-hour. One overtime hour earns one hour of leave. Simple to administer but does not account for the inconvenience premium employees might expect for unsociable hours.

Banked at the overtime rate. One overtime hour (which would have cost 1.5x pay) earns 1.5 hours of leave. This mirrors what the employee would have earned in cash terms. Some jurisdictions require this approach for TOIL (time off in lieu) to be treated as a lawful substitute for overtime pay.

Capped accrual. Employers set a maximum banked balance (e.g., 40 hours) to avoid large unfunded liabilities. Employees who hit the cap must take leave before accruing more, or the employer pays out.

Rolling expiry. Accrued time must be taken within a defined window (commonly 3 or 6 months) or it lapses. This controls balance growth but requires proactive scheduling.

A SHRM survey found that 37% of HR professionals cited tracking and reconciling comp time balances as a top administrative burden in flexible scheduling programs. The fix is almost always a written policy with clear expiry rules, not a more complex spreadsheet.

Legal and compliance considerations

United States. For private employers, comp time for non-exempt employees remains illegal under the FLSA in most circumstances. HR teams should assume the default position: pay overtime in cash for non-exempt workers unless operating under a specific state carve-out.

United Kingdom. The Working Time Regulations 1998 allow TOIL as an alternative to overtime pay, but the employee’s average weekly pay over the reference period cannot fall below the National Living Wage. Rest break entitlements (11 consecutive hours per day, 24 hours per week) cannot be waived in exchange for TOIL.

Australia. The Fair Work Act permits time off instead of overtime pay for full-time award-covered employees, provided: the arrangement is agreed in writing before the overtime is worked, the employee takes the time within 6 months, and the employer pays the overtime rate if the time is not taken.

European Union. The EU Working Time Directive caps working time at 48 hours per week (averaged over a reference period). TOIL is widely used but cannot override the maximum hours cap or minimum rest requirements.

For enterprise teams with cross-border workforces, the compliance matrix is non-trivial. Gartner research found that 58% of HR leaders identified inconsistent policy application across geographies as a top people-operations risk in 2024. A single global TOIL policy will not hold: you need jurisdiction-specific annexes.

How HR teams should track time in lieu

Accurate tracking is the operational backbone of any comp time program. Poor tracking leads to payroll disputes, audit exposure, and employee trust erosion.

What to track per employee:

• Date and hours of extra time worked
• Approved accrual rate (1:1 or 1.5:1)
• Running banked balance
• Approved TOIL requests and dates taken
• Expiry dates for each accrual block
• Manager approval record (timestamped)

This is distinct from general time-tracking. Time and attendance software that integrates comp time balance management eliminates the reconciliation gap between payroll and leave systems. Without integration, finance and HR end up reconciling two separate sources of truth at month-end, a process that compounds error risk.

Audit trail requirements. The FLSA requires employers to retain payroll records, including hours worked, for at least 3 years. Even if you are operating a comp time scheme for exempt employees (where FLSA overtime does not technically apply), documenting the arrangement protects you in any discrimination or wage claim.

Building a time in lieu policy: what to include

A compliant, scalable TOIL policy needs the following elements:

Scope. Which employee categories are covered (exempt, non-exempt, by jurisdiction)?

Accrual rate. Hour-for-hour or at the overtime premium rate?

Prior approval requirement. Extra hours must be pre-approved by the line manager, not self-authorised, for comp time to qualify.

Accrual cap. Maximum banked balance before the employer must pay out or mandate leave.

Expiry window. How long does accrued TOIL remain available? (3 months is common; 6 months for project-based roles.)

Request and approval process. How does the employee request TOIL leave? What is the turnaround time for approval? Can the employer defer the leave on operational grounds?

Payout on termination. What happens to unused TOIL when an employee leaves? Payout at base rate? At the overtime rate? Forfeiture (not recommended and potentially unlawful)?

Record-keeping. Who maintains the balance, in what system, with what audit trail?

Posting the policy in your employee handbook and requiring a signed acknowledgement at onboarding closes the paper-trail gap that creates disputes later.

Time in lieu and workplace flexibility

Time in lieu is one mechanism within a broader workplace flexibility framework. It serves a different purpose than remote work or flexible start times: it is specifically a compensatory tool for hours worked beyond contract, not a general schedule accommodation.

That distinction matters when communicating the program to employees. Conflating TOIL with “flex time” (where employees shift hours within their contracted total) creates expectation mismatches. A SHRM Flexible Work Survey found that employees ranked predictability of the policy rules second only to availability of the benefit itself when rating satisfaction with comp time programs.

For roles where overtime is structural (seasonal hiring surges, product launches, end-of-quarter reporting), TOIL offers a meaningful retention tool. A 2023 Mercer survey found that 44% of employees at large employers cited schedule recovery options after heavy work periods as a top retention factor, ranking above incremental base pay increases for knowledge workers.

Understanding how team leads apply TOIL policies fairly also ties into how you hire managers. Time and a half vs. comp time decisions require numerical reasoning and employment law awareness: competencies worth assessing in workforce management roles before promotion.
