Opinion for the Court filed by Senior Circuit Judge RANDOLPH.
A driver exceeding the speed limit runs a red light and swerves onto the opposite lane. Three violations of the law against reckless driving or one? Five punches to a victim’s face without provocation. One battery or five? Same result if the punches were hours apart? The financial officer of a corporation with 10,000 shareholders submits a false report to the Securities and Exchange Commission. One fraud or 10,000? These “unit-of-prosecution” questions have vexed state and federal courts. The questions are important. Prosecutors know that multiple charges encourage plea agreements and convictions. Defense attorneys know that it is easier to defend against one charge than many. Most people know that multiple offenses can result in multiple punishments.
Similar problems have dogged civil enforcement proceedings.
See, e.g., Missouri, Kansas & Texas Ry. Co. v. United States,
*466 The Secretary promulgates workplace “standards.” 29 U.S.C. § 655(b). A standard “requires conditions, or the adoption or use of one or more practices, means, methods, operations, or processes, reasonably necessary or appropriate to provide safe or healthful employment and places of employment.” Id. § 652(8). When the Secretary discovers that an employer has violated a standard, she may issue a citation and propose a financial penalty. Id. §§ 658(a), 659(a). Penalties vary with the severity of the violation: up to $7,000 for serious and other-than-serious violations, up to $70,000 for repeat violations, and between $5,000 and $70,000 for willful violations. Id. § 666(a)-(e).
The Occupational Safety and Health Review Commission, an independent tribunal, hears employer objections to the Secretary’s citations.
See Martin v. Occupational Safety & Health Review Comm’n,
The rulemaking here came in response to the Commission’s decision in
Sec. of Labor v. Erik K. Ho,
The Secretary’s new rules clarified that “each failure to provide [a respirator] to an employee” and “each failure to train an employee may be considered a separate violation.” 29 C.F.R. § 1926.20(f). The rulemaking amended thirty-three other standards to the same effect.
See Clarification of Employer Duty to Provide Personal Protective Equipment and Train Each Employee,
73 Fed.Reg. 75,568, 75,-583-89 (Dec. 12, 2008) (codified at 29 C.F.R. parts 1910, 1915, 1917, 1918 and 1926). Although the new rules authorize employee-by-employee charges, the Secretary’s Field Operations Manual states that generally only a single citation will issue for each standard an employer violates. Only when the employer’s behavior is willful and egregious does the manual contemplate multiple citations.

*467
Works, Inc. v. Sec’y of Labor,
Petitioners have one basic argument, which they repeat in many different forms. The argument is that under the Act, the Secretary had no authority to specify units of prosecution because Congress assigned such determinations to the Commission. We think there is nothing to the argument.
The unit of prosecution is derived from the duty set forth in the Secretary’s standard.
See, e.g., Chao,
Petitioners fail to recognize that to define the violation is to define the unit of prosecution. In the criminal law this basic proposition has long been established.
See, e.g., Crepps v. Durden,
(1777) 98 Eng. Rep. 1283, 1288 (K.B.) (Mansfield, J.);
In re Snow,
Reich v. Arcadian Corporation,
Petitioners insist that the Commission alone has the responsibility to determine units of prosecution because, under 29 U.S.C. § 666(j), the assessment of penalties is the Commission’s exclusive domain. This is like saying that in a criminal case the court — not the legislature — defines the unit of prosecution because the court has exclusive authority to determine the punishment. That of course is not the law.
See, e.g., Sanabria v. United States,
437
*468
U.S. 54, 69-70,
One final point deserves mention. Petitioners claim that we owe deference only to the Secretary’s interpretation of her own regulations, not to her interpretation of the Act. Circuit precedent is otherwise.
See Wal-Mart Stores, Inc. v. Sec’y of Labor,
The petition for judicial review is therefore denied.
So ordered.
