Regulación

Quién la regula y qué espera

El detalle normativo y de investigación de esta página se muestra en inglés.

Manufacturing has no fatigue-specific federal rule and no cap on hours. OSHA's process safety management standard, which governs the most hazardous plants in the country, says nothing about staffing, shift length or overtime - it requires only that the process hazard analysis address human factors. Federal wage law prices overtime and caps nothing. The real constraint is state law: New York, California, Illinois, Wisconsin and Massachusetts each require a day of rest in seven, and every one of them reaches factory work.

Occupational Safety and Health Administration — Regulado por

Quién la regula

OSHA is the governing safety regulator for US manufacturing, alongside the EEOC for disability accommodation and the Department of Labor for overtime and family and medical leave. The Chemical Safety Board investigates major process incidents and has repeatedly identified fatigue as a factor, but it makes recommendations only and cannot fine anyone. There is no dedicated fatigue regulator for the sector.

Sus obligaciones

Keep the plant free of recognized hazards, because no federal standard sets a maximum shift or a minimum rest period for manufacturing. Give a day of rest in seven where your state requires it: New York and Wisconsin for factories, Massachusetts for manufacturing and mechanical establishments, Illinois for twenty-four consecutive hours in every seven-day period, California for one day's rest in seven in any occupation. Address human factors in your process hazard analysis if you are a covered process. California refineries must go further and assess employee fatigue directly.

Consecuencias

OSHA can cite fatigue only as a recognized hazard under the general duty clause, which it must prove was recognized and workably fixable - a harder case than a standards citation. Day-of-rest breaches are enforced by state labor departments and carry their own penalties, in Illinois payable to the department and again to each affected employee. Fatigue-related injuries on the floor are compensable regardless of fault and raise the injury rates that put you on OSHA's targeting list. A diagnosed sleep disorder brings separate ADA and FMLA duties.

Sanciones

OSHA maximums at 2025 levels, in force for 2026: $16,550 per serious or other-than-serious violation ($1,085 minimum for serious), $165,514 per willful or repeat violation ($11,823 minimum for willful), $16,550 per day for failure to abate. Illinois day-of-rest penalties, at 2023 levels: $250 per offence to the department and up to $250 to each affected employee under twenty-five employees; $500 and $500 at twenty-five or more.

Fuentes: OSHA's General Duty Clause and its 2026 penalty schedule; OSHA's process safety management standard, 29 CFR 1910.119; OSHA's 2016 letter on shift work and fatigue; the Fair Labor Standards Act; the ADA and FMLA; the Chemical Safety Board's BP Texas City investigation.

Manufacturer pays $275,000 after firing worker it wrongly believed had disabling sleep apnea
- Legal
- Financiero
An industrial device manufacturer dismissed an employee because it assumed his sleep apnea and a heart condition made him unable to work. The Equal Employment Opportunity Commission sued under the Americans with Disabilities Act, saying the worker was fully capable of the job and was fired on stereotypes. The company settled for $275,000 and agreed to training and reporting obligations. The lesson: a sleep disorder should be assessed and managed, not treated as automatic grounds for dismissal.

Gas cylinder analyst found asleep at his desk is sent for fitness-for-duty checks; CPAP records show 30 minutes' use on 65 nights a year, and paid leave follows until use reaches 70%
- Legal
A long-serving specialty gas filler analyst at an industrial gas supplier's facility in New Hampshire, working a 2 p.m. to 11 p.m. shift, had sleep apnea and fell asleep during safety meetings; in 2014 he was drowsy and fell asleep while working, and the employer, treating the job as safety-sensitive, required a fitness-for-duty examination. His sleep doctor found he had used his CPAP machine an average of thirty minutes on only 65 of 365 days and advised him not to drive a forklift because of drowsiness; he was placed on a month's paid leave and cleared to return once CPAP use reached 70%, with continued usage monitoring. He resigned in 2015, and the federal court dismissed his discharge and retaliation claims but let his failure-to-accommodate (forklift) and whistleblower claims go forward.

Steel company owed no duty to motorist hit by night-shift mill worker who likely fell asleep driving home
- Seguridad
- Legal
A labor team leader at a steel company's mill worked a roughly 11-hour night shift (7:04 pm to 5:51 am), typical of hours he had worked five to six days a week for about three years, after about four and a half hours' sleep. At about 6:10 am, driving home, his car crossed the center line and hit an oncoming car head-on; he has no memory of the crash and assumes he fell asleep. The motorist suffered severe, permanent injuries, and her guardian argued the company owed a duty because it let him work long hours on consecutive days without a fatigue policy or training. The Indiana Court of Appeals affirmed summary judgment for the company, holding it owed no duty: the harm was foreseeable, but the relationship and public policy factors favored the employer, and limits on working hours were a matter for employers or the legislature.

Night-shift packer found 'completely asleep while packing parts' wins disability appeal; employer failed to finish interactive process
- Legal
A forming inspector and packer on the night shift at a manufacturing plant showed a pattern of decreased alertness and was found asleep at work, including completely asleep while packing parts. After a final warning she told the employer her problems might be medical, and her doctor's form marked a disability covered by federal disability law and noted excessive drowsiness, but she was terminated before narcolepsy was diagnosed. The federal appeals court held the employer knew of the possible disability before it fired her and had begun but not completed the interactive process required by that law, reversed summary judgment on the disability claim and sent it back to the district court.

Assembler who dozed off at work 'thousands of times' fired for sleeping on the job; no disability claim without employer knowledge
- Legal
An assembler at a surgical-equipment plant had a long history of daytime sleepiness and dozed off at work many times, including at plant-wide meetings. He was found asleep at his workstation, confirmed by two supervisors, and fired the next day under a first-offense policy. Obstructive sleep apnea was diagnosed only after the firing. The federal appeals court held the disability discrimination claim failed because the company had no actual knowledge of a sleep disorder when it acted.

Seat builder with narcolepsy quits over a one-hour later start; federal disability law does not require a schedule change for an easier commute, appeals court rules
- Legal
A prototype seat builder at an automotive seating plant in Michigan had medication-treated narcolepsy and a commute of two to four hours. When her department's 6 a.m. to 3 p.m. hours were moved one hour later, she said heavier traffic would tire her more quickly on the drive and asked to keep the earlier start, and she resigned when that was not granted. The U.S. Court of Appeals, even assuming she was disabled, held that a changed schedule to commute in lighter traffic was not a reasonable accommodation that federal disability law required, and upheld judgment for the employer.

Chemical plant staff on 60-70 hour weeks through a troubled restart; runaway reaction explosion kills two workers and CSB flags operator fatigue
- Seguridad
A runaway chemical reaction caused a pressure vessel to explode during the restart of a pesticide production unit at a chemical manufacturer's plant in West Virginia, and two employees sent to check the vessel died. The U.S. Chemical Safety Board found that many operators and key staff had been working 60 to 70 hours a week before the startup, some reporting 18-hour shifts with 6 hours off, and judged the control panel operator likely fatigued after an 84-hour week. The Board could not determine whether fatigue specifically contributed, but recommended an independent human factors study of operator fatigue in the site's control rooms.

Tractor operator with sleep apnea laid off the day he asks to come off a new rotating shift; appeals court revives his disability claim
- Legal
- Financiero
A tractor operator at a metal manufacturing plant in Illinois had fibromyalgia and obstructive sleep apnea, with a 2007 sleep study rating his sleep efficiency "very poor at 48%", and his doctors had him on straight day shifts without overtime. When a 2007 reorganisation moved his job to rotating day, evening and night shifts, he tried it for two weeks, then presented a doctor's note restricting him from the rotation and was laid off that day; he was not placed in another job until a straight-day post opened later in 2007. The U.S. Court of Appeals reversed summary judgment for the employer on his federal disability discrimination claim, holding that a jury could find his sleep problems a disability and that there was a genuine dispute over whether overtime was an essential function of the open straight-day jobs he was not offered.

Evening-shift electrician with narcolepsy-like disorder seeks day shift; firing over undisclosed narcolepsy upheld
- Legal
An electrician on the 4 p.m. to 12:30 a.m. shift at a car maker's assembly plant had a narcolepsy-like disorder and found himself missing his turn while driving home late at night. His doctor asked for a regular day shift on medical grounds. The car maker then fired him for allegedly lying on its medical history form and on a driver's license examination form that asked whether he had ever had narcolepsy. The federal appeals court upheld summary judgment for the car maker because it had reasonably relied on particularized facts for the driver's license form reason.

Flooring plant worker who nodded off for a minute or two at her station is reinstated; employer must weigh unintended dozing differently from planned sleeping
- Legal
A worker with an unblemished eight-year record at a hardwood flooring plant in Tennessee was fired in 1991 for sleeping on the job. An arbitrator found she had fallen asleep at her work station, probably for no "more than a minute or two", but held the firing lacked just cause because the company ignored mitigating factors, including her lack of intent, and treated her the same as an employee who had built a shack to hide out and sleep; the arbitrator substituted a ten-day suspension with back pay. The U.S. Court of Appeals reversed the district court and reinstated the arbitrator's award.

Glass plant supervisor sent on a 50-mile overnight assignment blacks out at the wheel after about 27 sleepless hours; court rules the whole drive home was work

- Legal
A salaried supervisor at a glass manufacturer's plant in New Jersey was told near the end of his day to travel about 50 miles to a customer to investigate a glass problem. He worked there through the night until 8 a.m., then blacked out at the wheel on the way home and collided head-on with another vehicle. The New Jersey Appellate Division held the entire journey was part of the assignment, citing the roughly 27 sleepless hours and the fatigue hazard the employer's errand created, and affirmed workers' compensation.

Glass plant bricklayer crashes minutes after a long, hot furnace shift; fatigue award upheld
- Seguridad
- Legal
A veteran bricklayer laying firebrick in a glass furnace at a glass company worked 9 hours 15 minutes in very hot conditions, longer than the normal 8-hour day, because the employer wanted the furnace job finished quickly. Minutes after leaving the plant his car left the highway about a mile away and he was seriously injured. The Workers' Compensation Board awarded permanent total disability benefits, and in 1976 the Minnesota Supreme Court affirmed, holding the Board could reasonably infer he lost consciousness from fatigue caused by his work.
