Your best advice comes after a good night’s sleep.
Office-based work with long billable hours and deadline peaks that cut sleep short. The direct safety consequence is low; poor sleep costs judgment, errors, productivity and retention.
No professional conduct rule in law or accounting names fatigue. The competence rule requires the knowledge, skill, thoroughness and preparation reasonably necessary, and says nothing about the condition of the person supplying them. Nor does wage law help: at the salary level currently enforced almost every associate, consultant and senior accountant is exempt from overtime, so busy season carries no pay penalty and produces no hours record any regulator sees. Your billable-hours system is the only record, and it was built to price work, not to manage risk.
Regulated by
OSHA
Logos identify the regulator and don’t imply endorsement.
Who regulates it
OSHA for workplace safety, the EEOC for disability accommodation, the US Department of Labor for family and medical leave and the overtime-exemption rules, and your state workers' compensation system. State bar associations and boards of accountancy govern competence and diligence in professional work, but as conduct standards - none of them regulates hours or fatigue.
Your obligations
Keep your workplace free of recognized hazards likely to cause death or serious harm. Fatigue is not named in that duty, so it has to be shown as a recognized hazard with a feasible control. Supervise the work of junior practitioners competently. Accommodate a diagnosed sleep disorder through the interactive process. If you screen your people, run it as a voluntary health program with results on separate forms in separate confidential medical files, and take no adverse action on a refusal. In California, give every worker one day's rest in seven.
Consequences
A citation for leaving a recognized fatigue hazard unaddressed comes with an abatement order and a public record. In practice the sharper exposures are elsewhere: a fatigue-driven error in regulated professional work is a malpractice claim and a conduct complaint at the same time, and a fatigued practitioner driving home from a late close is a third-party negligence claim your workers' compensation cover does nothing about. Screening handled badly is a discrimination charge and federal litigation.
Penalties
OSHA maximums are at 2025 levels and carry into 2026 unchanged, because the federal inflation adjustment was cancelled this year: $16,550 per serious or other-than-serious violation, $165,514 per willful or repeat violation, and $16,550 per day for failure to abate. Disability discrimination damages are capped by headcount from $50,000 to $300,000. Professional discipline and malpractice exposure carry no fixed maximum.
On the record
No US court, coroner, investigator or regulator has published a finding linking fatigue to an incident in professional services. Fatigue still falls under OSHA's General Duty Clause as a recognized hazard.

Fatigue-critical roles
Where fatigue matters most in professional services
The roles where a fatigued worker is most likely to cause serious harm, the tasks that carry the risk, and why fatigue builds up in them.
Role
Risk
High-risk tasks
Why fatigue builds
Field / geotechnical engineerRules
Regulatory designation
Miner under MSHA training rules when on a mine site (30 CFR Part 46/48); otherwise general duty
Hours and rest
No federal hours cap for adults; FLSA prices overtime only
High risk
Site inspections on mines and construction sites, working near mobile plant and at height, long drives on unsealed roads, FIFO travel days
FIFO/DIDO rosters (e.g. 8/6, 14/7) with 12 h shifts, early charter flights, long regional drives
Field engineer / construction manager (railroad or highway night work)Rules
Regulatory designation
Roadway worker (49 CFR 214.7) when on railroad track; otherwise general duty
Hours and rest
None - hours-of-service laws cover train, dispatching and signal employees (49 U.S.C. 21103-21105), not roadway workers
High risk
Supervising track or road works in overnight possessions or closures near live traffic or rail, protection arrangements, sign-off to hand back the asset by 05:00
Consecutive night shifts (22:00-06:00) and weekend possessions, day-to-night swaps, long drives home at dawn
Associate (BigLaw)Rules
Regulatory designation
None specific - general duty (OSH Act s 5(a)(1); public employers only in State Plan states)
Hours and rest
No federal hours cap for adults; FLSA prices overtime only
Elevated risk
Drafting and verifying signing documents through the night before closing, disclosure and filing deadlines, where an error causes major client loss
70-90 h weeks during transactions, all-nighters before signing, cross-time-zone calls
How the suite fits
How each product connects to your obligations
Grades describe how strongly a product connects to an obligation. None discharges an obligation, and none carries a compliance warranty.
Sleepfit
Supports your general duty of care
Sleepfit measures sleep obtained across your practice and screens for the disorders behind it, supporting the recognized-hazard case you would make to OSHA. Results are confidential and aggregated.
Awareness eLearning gives your practice a documented fatigue education record. No US rule requires it; it evidences a feasible abatement measure if OSHA ever puts a recognized hazard to you.
29 CFR Part 1904 requires you to record injuries, not to investigate their cause, and no US rule names a fatigue review. Was It Fatigue? supports your own investigation. A structured judgment aid, not a determination of cause.
SleepWellBaby supports parents returning to work after a birth, when broken infant sleep is at its worst. No US regulation requires it and none is engaged; it is offered as a benefit, not an obligation.
Fatiguefit4Duty is built for safety-sensitive roles at the point of duty. Professional services roles are generally not safety-sensitive and no US rule requires a fitness-for-duty check, so nothing is engaged.
Your practice teams hold no safety-sensitive roles, so your duty is the General Duty Clause, OSH Act s 5(a)(1). Sleepfit screens confidentially; Awareness eLearning supplies content with a completion record; SleepWellBaby is an employee benefit. Family is the lighter option.
