STRUCTURAL NOTE 03 · WORKING TIME

Two things are labeled "agreement." Only one sits in the hierarchy. The other stands beside it.

労働法規は上位規範が下位を制約する序列で積み上がる。しかし労使協定（36協定等）はこの序列の一段ではなく、労働基準法上の一般的禁止に対する「例外を可能にする別枠の仕組み」。

THE LADDER, AND WHAT STANDS BESIDE IT効力の序列／労使協定は序列の一段ではない

The Constitution憲法

Laws and Regulations法令

The statutory floor. MHLW circulars sit beside this as interpretation only.

Collective Agreement労働協約

Union ↔ employer, normative effect for covered workers.

Rules of Employment就業規則

Per workplace. May not fall below 02 or an applicable 03.

Individual Labor Contract労働契約

Terms below 04 are pulled up to it.

NOT A RUNG · 序列の外

Labor-Management Agreement 労使協定

A statutory exception mechanism standing beside the ladder. It permits what the Act generally prohibits — it does not rank above or below anything, and it commands nothing.

→ ENABLES AN EXCEPTION AT 02

→ NEEDS A DUTY AT 04 OR 05

Japanese labor rules stack in a defined order of precedence — a lower rule is constrained by the applicable higher norms above it. But the Labor-Management Agreement (of which the Article 36 agreement is one) is not a rung on this ladder.

Many labor-management agreements operate as statutory exception mechanisms under the Labor Standards Act. The Article 36 agreement is the clearest example and has an exemption-from-penalty effect. Treating one as "the top layer that overrides the rest" is the classic misread — and it is why overtime needs two things, not one.

The hierarchy

LOWER RULES ARE CONSTRAINED BY APPLICABLE HIGHER NORMS · 効力の序列

The legal effect is not identical at every level. Where a higher rule establishes an applicable minimum standard, a lower term cannot fall below it.

01 The Constitution of Japan 憲法A lower rule is constrained by the applicable higher norms.

02 Laws and Regulations 法令（労働基準法等）The statutory floor. MHLW circulars sit beside this as interpretation only — they are guidance, not law.

03 Collective Agreement 労働協約Labor union ↔ employer. Applies with normative effect to workers covered by the agreement.

04 Rules of Employment 就業規則Per workplace. May not fall below the Laws and Regulations or an applicable Collective Agreement.

05 Individual Labor Contract 労働契約The floor of the stack. Terms below the Rules of Employment are pulled up to them.

Beside the ladder

労使協定 — NOT A LAYER, A SEPARATE MECHANISM

It does not rank above or below anything. When their conditions are met, many labor-management agreements let the employer use a permitted exception to a general prohibition in the Labor Standards Act. The Article 36 agreement is the clearest example — it has an exemption-from-penalty effect under the Act.

EXAMPLES OF THE MECHANISM

Article 36 agreement — overtime work / work on days off · Variable Working Hours Systems — some require a written labor-management agreement · Flextime system — settlement-period hours · Simultaneous-break waiver — staggered breaks · Wage-deduction agreement — partial deductions from wages

IT PERMITS — IT DOES NOT COMMAND

A valid Article 36 agreement, once filed, allows the employer to have workers perform overtime within the agreement and statutory limits without violating the Act. But it does not, by itself, oblige any individual to work it. The private-law duty must exist separately — in the Rules of Employment (04) or the Individual Labor Contract (05).

WHAT THIS MEANS FOR YOUR POLICY

Overtime is authorized only when both are present at once.

A valid Article 36 agreement — public-law authorization, filed for the relevant workplace, specifying the range of workers and a one-year applicable period — and a private-law obligation somewhere in the hierarchy. Model them as two independent gates. The authorization without the obligation still leaves nothing to enforce; the obligation without a valid, in-force agreement is unlawful to act on.
