Almost everything people believe protects their schedule — the vote, the hardship rule, the years they have worked it — protects something narrower than they think. Read what actually protects it before assuming any of it applies to you.
I Two systems, not one
“AWS” covers two legally distinct things, and people routinely argue about one while holding rights under the other.
| Flexible (FWS) | Compressed (CWS) | |
|---|---|---|
| Authority | 5 U.S.C. 6122 | 5 U.S.C. 6127 |
| What varies | When you work, within core hours | How many days you work |
| Typical form | Flexitime, maxiflex | 4/10, 5/4/9 |
| Credit hours | Yes — 5 U.S.C. 6126 | No |
| Excess hours are | Credit hours or overtime | Overtime |
| Vote to establish | Not required | Required in an unorganized unit |
Maxiflex is a flexible schedule, not a compressed one. That single misclassification causes more confusion than anything else in this area, because someone on maxiflex arguing about the compressed schedule rules is arguing from the wrong section of the statute.
A 4/10 is four ten-hour days — a day off every week. A 5/4/9 is eight nine-hour days plus one eight-hour day across the pay period — a day off every two weeks. The statute also permits other compressed arrangements, so long as the hours add up.
Neither programme requires OPM approval to establish. Agencies may set them up under 6122 or 6127 on their own authority, covering employees of any executive agency other than the Postal Service, any military department, the Government Publishing Office and the Library of Congress.
II Credit hours, and where they do not exist
Credit hours are hours you elect to work in excess of your basic requirement, banked and used later as time off. They are a feature of flexible schedules under 5 U.S.C. 6126.
They are not permitted under a compressed work schedule. For a full-time employee on a CWS, all hours worked in excess of the established schedule are overtime hours. Compensatory time off may be requested only for irregular or occasional overtime work — and may not be approved for any member of the Senior Executive Service.
Someone moving from a flexible to a compressed schedule loses the ability to bank credit hours entirely. If you have relied on credit hours to manage appointments or family obligations, that is a real change in working conditions and not merely a change in start times. The premium pay mechanics are in overtime and premium pay.
III The majority vote
Under 5 U.S.C. 6127(b)(1), a compressed work schedule may not be established in an unorganized unit unless a majority of the employees who would be included vote to be included.
OPM treats a majority as obtained when affirmative votes exceed 50 percent of the number of employees and supervisors in the organisation proposed for inclusion. Note the denominator: it is everyone proposed for inclusion, including supervisors — not everyone who voted.
It stops an agency imposing a compressed schedule on unrepresented employees who do not want one. It does not stop an agency ending a schedule that employees do want. Those are different acts and only one of them requires a vote. People frequently cite the vote as evidence that their schedule cannot be taken away; it is evidence of no such thing.
IV Schedule & Protection Check
What your schedule gives you in days off and credit hours, and what — if anything — actually protects it.
What Do I Have, and What Protects It?
Estimates only. Your agency policy and any collective bargaining agreement govern the specifics.
V The hardship exclusion
Section 6127(b)(2) requires that any employee for whom a compressed work schedule would impose a personal hardship be excluded from the schedule or reassigned. Each agency should have a procedure for requesting exclusion, and the agency decides whether a hardship exists.
Neither the statute nor its legislative history defines personal hardship. OPM guidance directs agencies to be sensitive to the possibility that a compressed schedule could adversely affect certain employees — particularly disabled employees and those responsible for the care of disabled family members or dependent children — and notes that other valid hardship situations may arise depending on the facts.
The hardship exclusion protects you from being put on a compressed schedule. It is not a mechanism for keeping one. If a ten-hour day would be genuinely unworkable for you, this is the provision to cite — and where the difficulty stems from a disability, reasonable accommodation is a separate and often stronger route that runs on its own framework.
VI What actually protects a schedule
An agency may end an AWS programme on a finding of adverse agency impact — a reduction in productivity, a reduction in the level of service to the public, or an increase in the cost of agency operations. The criteria and review provisions are at 5 U.S.C. 6131.
Those grounds are broad, the agency makes the finding, and no OPM approval is needed. So what has actually constrained agencies is not the statute.

Same statute. Opposite outcomes. The variable was the contract.
The practical conclusion for anyone whose schedule matters to them: find out whether you are covered by a current collective bargaining agreement, and what it says about work schedules. If you are not covered, your schedule rests on agency discretion — which can be exercised by email, as it was. See union representation and grievance procedures.
VII The coercion prohibition
There is a statutory prohibition of coercion at 5 U.S.C. 6132, addressing interference with an employee's rights under the subchapter — including in connection with the votes the subchapter provides for.
If you are being pressured over a schedule election or a vote, that provision is worth raising by name, and the conduct may engage other protections depending on the circumstances. As always, build the record first: keep a contemporaneous note of what was said, by whom, and when, before raising anything. See documenting everything.
VIII The playbook
| Situation | What to do |
|---|---|
| You value your schedule | Find out whether a current collective bargaining agreement covers it. That is the protection. |
| Not represented | Your schedule rests on agency discretion. Plan on that basis. |
| Agreement recently rescinded | The constraint that was protecting the programme is gone. Expect change. |
| Told the vote protects you | It does not. The vote governs imposing a CWS, not ending one. |
| Moving from flexible to compressed | You lose credit hours entirely. Raise it as a change in working conditions. |
| Ten-hour days would be unworkable | Cite the 6127(b)(2) personal hardship exclusion, in writing. |
| Hardship stems from a disability | Reasonable accommodation is a separate and usually stronger route. |
| On maxiflex | That is a flexible schedule. Do not argue it under the compressed rules. |
| Pressured over a vote | 5 U.S.C. 6132 prohibits coercion. Document first, then raise it. |
| Programme being ended | Ask what adverse agency impact finding was made under 6131, in writing. |
Understanding your position
- Identify whether your schedule is flexible or compressed — they are different statutes.
- Confirm whether you are in a bargaining unit with a current agreement.
- Read what that agreement says about work schedules.
- If you are not covered, accept that the schedule is discretionary.
- Check whether you can earn credit hours, and what happens if you cannot.
- Find your agency's procedure for requesting a hardship exclusion.
- If a change would create genuine hardship, put the request in writing early.
- Where disability is involved, pursue reasonable accommodation separately.
- If a programme is ended, ask for the adverse agency impact finding.
- Keep a record of anything said to you about schedule votes or elections.
Frequently asked questions
A flexible schedule varies when you work within a set of core hours and bands, and is authorised by 5 U.S.C. 6122. A compressed schedule fixes when you work but packs the same hours into fewer days, and is authorised by 5 U.S.C. 6127. A 4/10 is four ten-hour days with a day off every week; a 5/4/9 is eight nine-hour days plus one eight-hour day across a pay period, with a day off every two weeks. Maxiflex is a flexible schedule, not a compressed one, which matters because the two are governed by different provisions.
No. Credit hours exist under 5 U.S.C. 6126 as a feature of flexible schedules only, and they are not permitted under a compressed work schedule programme. For a full-time employee on a compressed schedule, all hours worked in excess of the established schedule are overtime hours rather than credit hours. An employee on a compressed schedule may request compensatory time off only for irregular or occasional overtime work, and compensatory time off may not be approved for any member of the Senior Executive Service.
No. Agencies wishing to establish flexible or compressed work schedules permitted under 5 U.S.C. 6122 or 6127 do not need OPM approval. The programmes may apply to employees of any executive agency other than the Postal Service, any military department, the Government Publishing Office, and the Library of Congress. The absence of an approval requirement cuts both ways: the same discretion that lets an agency create a programme without asking anyone lets it end one.
Under 5 U.S.C. 6127(b)(1) a compressed work schedule may not be established in an unorganized unit unless a majority of the employees who would be included vote to be included. OPM treats a majority as obtained when affirmative votes exceed 50 percent of the number of employees and supervisors in the organisation proposed for inclusion. It is worth being precise about what this protects: it stops an agency imposing a compressed schedule on unrepresented employees who do not want one. It does not stop an agency from ending a schedule people do want.
Yes. Section 6127(b)(2) requires that any employee for whom a compressed work schedule would impose a personal hardship be excluded from the schedule or reassigned. Each agency should have a procedure for requesting exclusion, and the agency determines whether a hardship exists. Neither the statute nor its legislative history defines personal hardship, but OPM guidance directs agencies to be sensitive to the possibility of adverse effects on disabled employees and on those responsible for the care of disabled family members or dependent children.
In most circumstances, yes. Alternative work schedules are management-run programmes rather than individual entitlements, and an agency may end one on a finding of adverse agency impact — meaning a reduction in productivity, a reduction in the level of service to the public, or an increase in the cost of agency operations. The criteria and review provisions sit at 5 U.S.C. 6131. Where employees are represented, a collective bargaining agreement has historically been the real constraint on that discretion.
The same statute produced opposite outcomes at different agencies, which illustrates the point better than any explanation. The IRS ended compressed schedules effective 25 July 2026, an action that became possible after it rescinded its national agreement with NTEU in February 2026 — a materially identical attempt in 2025 had been challenged under that contract and did not stand. In the same year the Department of Homeland Security reinstated alternative work schedules for a very large share of its workforce. Nothing in the law changed between those two outcomes.
There is a statutory prohibition on coercion at 5 U.S.C. 6132, which addresses interference with an employee's rights under the subchapter, including in connection with the votes the subchapter provides for. If you believe you are being pressured over a schedule election or a vote, that provision is worth raising by name, and the conduct may also engage other protections depending on the circumstances. Keep a contemporaneous record of what was said and by whom before raising anything.
