Flexible Work Schedules for Federal Employees: Types and Pay

Federal employees can work non-standard hours under the Federal Employees Flexible and Compressed Work Schedules Act of 1982, which lets agencies offer alternatives to the traditional eight-hour, five-day workweek.¹ Flexible work schedules for federal employees come in five varieties defined by the Office of Personnel Management, and they sit alongside two compressed schedule options. Each type has its own rules on core hours, credit hours, overtime, and holiday pay, and no employee has an automatic right to any of them. Your agency head decides which schedules to offer and can restrict or end them.

The Five Flexible Schedule Types

OPM’s Handbook on Alternative Work Schedules defines five specific flexible arrangements.² All of them share two structural pieces: core hours when you must be present, and flexible bands where you choose your own start and stop times. What separates them is how much you can shift hours between days and weeks.

Flexitour. You pick your start and stop times from within the flexible bands, and those times become your fixed daily schedule until the agency lets you choose again.
Gliding schedule. You still work eight hours a day and 40 hours a week, but you can change arrival and departure times each day within the flexible bands.
Variable day. You can vary how many hours you work on a given day, as long as each week totals 40 hours.
Variable week. Same idea, but the balancing window stretches to the full 80-hour biweekly pay period. Forty-four hours one week and 36 the next is fine.
Maxiflex. The most adaptable option. Core hours appear on fewer than ten workdays in the pay period, and you can vary both the length of your workday and which days you work, as long as you hit 80 hours over the two weeks.

Not every agency offers all five. The statute authorizes each agency head to restrict arrival and departure choices, limit credit hour use, or exclude certain employees based on operational needs.³ Maxiflex in particular is rare outside agencies with dispersed teams or 24-hour operations, because the reduced core-hour requirement makes coordination harder.

Core Hours and Flexible Bands

Every flexible schedule designates core hours, the window when all employees on that schedule must be at work. Setting those hours and days is a statutory condition of offering flexible schedules at all.³ A typical core period might run from 10:00 a.m. to 2:00 p.m., with flexible bands from 6:00 a.m. to 10:00 a.m. and 2:00 p.m. to 6:00 p.m. If you are not working during core hours, you need to be on approved leave or using earned credit hours.

Maxiflex is the exception: it has core hours on fewer than ten workdays in the pay period, which is what lets employees take entire days off without using leave. Variable day and variable week schedules require core hours on every workday. The specific hours and bands vary by agency and sometimes by office, so check your agency’s policy before assuming.

Credit Hours

Credit hours are what make flexible schedules genuinely flexible. Under a flexible schedule, you can voluntarily work beyond your basic requirement and bank the extra hours to shorten a future workday or take time off.⁴ The word “voluntarily” matters. If your supervisor orders the extra work, those hours are overtime, not credit hours, and they trigger a different pay calculation.⁵

Carryover limits are strict. Full-time employees can carry a maximum of 24 credit hours from one biweekly pay period to the next. Part-time employees can carry over no more than one-fourth of the hours in their biweekly basic work requirement.⁴ Anything above the cap at the end of a pay period is lost. Your agency or union agreement may impose tighter limits still.⁶

Travel and Training

You generally cannot earn credit hours while traveling, because travel is ordered by the agency rather than elected by you. OPM allows a narrow exception when you perform productive work during travel that is voluntary, exceeds your basic requirement, and falls within your agency’s designated credit-hour window.⁶ Required training is treated the same way: the agency is directing the work, so the hours are not voluntary and do not earn credit. Your agency may put you on a standard schedule during training to avoid confusion.

Leaving the Program

If you leave a flexible schedule for any reason, whether transfer, reassignment, or termination of the program itself, accumulated credit hours are paid out at your current basic pay rate. Full-time employees are paid for up to 24 hours; part-time employees for up to one-fourth of their biweekly basic requirement.⁴

Compressed Schedules Are the Other Option

Compressed schedules work on a different principle. Where flexible schedules shift when hours happen, compressed schedules are fixed: longer days in exchange for a regular day off.⁷ The two common versions are the 4-10 schedule (four ten-hour days each week with one day off) and the 5-4-9 schedule (eight nine-hour days, one eight-hour day, and one day off across the biweekly pay period).⁸

The critical practical difference: compressed schedules do not allow credit hours. You cannot voluntarily work extra time on a compressed schedule and bank it.⁷ Anything beyond your established compressed schedule counts as overtime and must be officially ordered in advance.

How These Schedules Affect Your Pay

Holidays

Holidays are where flexible and compressed schedules diverge sharply. On a flexible schedule, when a federal holiday falls on a workday, you receive eight hours of holiday credit toward your biweekly requirement, no matter how many hours you were scheduled that day.⁹ A planned ten-hour day means you’ll need to make up the extra two hours elsewhere or use leave or credit hours.

Compressed schedules pay for the full scheduled day. If a holiday falls on one of your compressed workdays, you receive pay for however many hours you were scheduled, so a ten-hour compressed workday on a holiday means ten hours of holiday pay.¹⁰ That’s a genuine financial advantage of compressed scheduling.

Night and Sunday Pay

If your flexible schedule has at least eight hours available for work between 6:00 a.m. and 6:00 p.m., you do not earn night pay for voluntarily working flexible hours after 6:00 p.m., including while earning credit hours. You do earn night pay for hours between 6:00 p.m. and 6:00 a.m. that are part of designated core hours or that you must work to complete an eight-hour daily tour.¹¹ Sunday premium pay applies to full-time employees who perform nonovertime work on a regularly scheduled tour that begins or ends on Sunday, covers up to eight hours, and does not extend to leave, holidays, or excused absence.⁵

Who Qualifies and How to Request One

No federal employee has an automatic right to a flexible or compressed schedule. Each agency head decides whether to establish these programs and can restrict or end them.³ Eligibility usually depends on whether your duties are compatible with non-standard hours. Positions that require physical presence at secure facilities, emergency response roles, and jobs tied to specific public-service windows are commonly excluded.

For bargaining-unit employees, any flexible or compressed schedule, and any decision to establish or terminate one, must comply with the collective bargaining agreement between the agency and the union.¹² An agency cannot unilaterally pull a schedule that was negotiated into the contract.

To request a schedule, start with your agency’s internal policy on alternative work schedules to see which types are offered, what the core hours are, and which flexible bands apply. Your proposed schedule should lay out arrival and departure times for each day of the biweekly pay period, adding up to 80 hours for full-time employees while covering all designated core hours. Most agencies handle submissions through an HR portal or the electronic time-and-attendance system. The request goes to your immediate supervisor first, then to HR for compliance review. If a request is denied, ask for the reason in writing; a documented denial is useful if you want to revisit it later or if a union grievance becomes relevant.

When an Agency Can End Your Schedule

An agency head can terminate a flexible or compressed schedule by finding “adverse agency impact” under 5 U.S.C. 6131. The finding must show that the schedule has caused or would cause reduced productivity, diminished public service, or increased operating costs beyond reasonable administrative setup costs. If the finding is made, the agency must discontinue the schedule.¹³

For non-bargaining-unit employees, that is essentially the end of the road. There is no statutory appeals process; your options come down to internal grievance procedures or working with your supervisor on an alternative. For union-represented employees, termination goes through collective bargaining, and unresolved disputes go to the Federal Service Impasses Panel, a body within the Federal Labor Relations Authority.¹⁴ Until the Panel issues a final decision, the existing schedule generally stays in place.¹³

Telework Is a Separate Program

Flexible work schedules govern when you work. Telework governs where you work. Having one does not entitle you to the other. A federal employee can have a gliding schedule and still be required to report to the office every day, or can telework three days a week on a standard 8:00-to-4:30 schedule. A January 2025 executive order directed agency heads to terminate remote work arrangements and return employees to in-person work on a full-time basis, with exemptions left to agency discretion.¹⁵ That order targets remote work and telework, not alternative work schedules. Your 5-4-9 compressed schedule or gliding flexible schedule rests on a separate legal authority under the 1982 Act and is not automatically affected by return-to-office directives, though the broader push toward in-office presence may influence how liberally agencies approve arrangements that reduce the days employees appear at the workplace.
