In many cases, yes. Most U.S. workers are employed "at will," which means an employer can generally cut your hours, change your schedule, or discipline you for missing work, including for being sick, unless a specific law, contract, or policy protects the absence. The key question is why the action happened: if your hours were cut because you used legally protected sick leave or a protected medical right, that can be illegal retaliation, even though the same hour cut would be perfectly lawful in other circumstances.
This article explains the federal baseline, where state law tends to add stronger protections, and what to actually do if you think you were punished for being sick.
The Default Rule: At-Will Employment
Unless you have a written contract, a union collective bargaining agreement, or a civil-service job that says otherwise, you are most likely an at-will employee. Under at-will employment, your employer can change your schedule, reduce your hours, move you to a less desirable shift, or even fire you for almost any reason, or no reason at all. There is no general federal law that guarantees a private-sector worker a minimum number of hours or paid sick days.
So an employer who cuts the hours of a worker who keeps calling in sick is often acting within the law, frustrating as that is. The protections kick in only when the reason for the cut crosses into territory that a specific statute forbids. That is why "why did this happen?" matters far more than "is cutting hours allowed?"
When Cutting Hours or Punishing Sickness Becomes Illegal
Several federal laws turn an otherwise-lawful hour cut into unlawful retaliation or discrimination when the absence was protected. The most common ones:
Family and Medical Leave Act (FMLA)
The FMLA, enforced by the U.S. Department of Labor Wage and Hour Division, gives eligible employees up to 12 weeks of unpaid, job-protected leave per year for a serious health condition (their own or a close family member's), among other reasons. It is unlawful for an employer to interfere with FMLA leave or to retaliate against you for taking it, and that includes cutting your hours, demoting you, or scoring you negatively under an attendance point system for FMLA-protected absences.
The FMLA does not cover everyone. It generally applies to employers with 50 or more employees within 75 miles, and you typically must have worked there about a year and at least 1,250 hours in the prior 12 months. A common cold usually is not a "serious health condition," but conditions requiring inpatient care or ongoing treatment often qualify.
Americans with Disabilities Act (ADA)
If your illness is a disability, or a chronic condition that substantially limits a major life activity, the ADA, enforced by the Equal Employment Opportunity Commission (EEOC), may require your employer to provide reasonable accommodations. That can include time off, a modified schedule, or leave as an accommodation, unless it causes the employer undue hardship. Punishing you, including by cutting hours, because you needed accommodation for a disability can be unlawful disability discrimination and retaliation. The ADA generally covers employers with 15 or more employees.
Title VII (Pregnancy and Related Conditions)
Under Title VII and the Pregnancy Discrimination Act, also enforced by the EEOC, an employer cannot penalize you for pregnancy-related medical needs. The newer Pregnant Workers Fairness Act further requires reasonable accommodations for pregnancy, childbirth, and related conditions for covered employers.
State and Local Paid Sick Leave Laws
This is where protection varies widely. Many states and cities have passed mandatory paid sick leave laws that let you earn and use a set amount of sick time, and that expressly prohibit retaliation, including cutting hours, for using it. If you work somewhere with such a law and your hours were slashed after you used protected sick time, that may violate state law even if no federal statute applies. This varies by state (and even by city), so check your state labor department or local ordinance for the specific rules, accrual rates, and deadlines that apply to you.
Other Protected Reasons
Hour cuts can also be illegal when tied to: filing a workers' compensation claim after a workplace injury; reporting unsafe conditions under OSHA; taking protected leave for military or jury service; or engaging in "concerted activity" with coworkers about working conditions, which the National Labor Relations Act (NLRA) protects through the National Labor Relations Board, even in non-union workplaces.
Hour Cuts as an "Adverse Action"
People sometimes assume retaliation only counts if you are fired. It does not. Reducing your hours, cutting your pay, stripping you of a good shift, or making conditions so bad you feel forced to quit ("constructive discharge") can all qualify as an adverse employment action in a retaliation or discrimination claim. If an employer cannot legally fire you for using protected leave, it generally cannot legally accomplish the same punishment by quietly choking off your hours instead. What you need to show is a connection between your protected activity (using the leave) and the negative action (the hour cut), often supported by timing, comments, and inconsistent treatment compared with other workers.
Attendance Points and "No-Fault" Systems
Many employers use attendance point systems where every absence earns a point, and too many points trigger discipline or termination. These systems are legal in general, but they become a liability when they assign points for legally protected absences. Counting an FMLA day, an ADA accommodation day, or a protected paid-sick-leave day against you can itself be unlawful. If you are being disciplined under a point system, look closely at whether any of the points came from protected absences.
What to Do If You Think You Were Punished for Being Sick
Acting methodically makes a big difference if this ever becomes a formal dispute.
- Document the timeline. Write down when you got sick or requested leave, what you told your employer and when, and exactly when your hours were cut or discipline was issued. Tight timing between the two is powerful evidence.
- Save everything in writing. Keep texts, emails, schedules, pay stubs, attendance records, doctor's notes, and any written policy on sick leave or attendance. Email yourself a dated summary so you have a contemporaneous record.
- Compare your treatment. Note whether coworkers who did not use sick leave kept their hours or shifts. Different treatment for similar situations supports a retaliation claim.
- Ask for the reason in writing. A neutral, non-accusatory email ("Can you help me understand why my hours were reduced?") can lock in the employer's stated reason, which matters if that reason later shifts.
- Check your handbook and any contract. Company policy, an offer letter, or a union agreement may give you more rights than the legal minimum.
- Request leave properly. If you have a serious or chronic condition, formally requesting FMLA leave or an ADA accommodation in writing creates protected status and a paper trail.
Where and How to File a Complaint
The right agency depends on the law involved:
- FMLA interference or retaliation: file with the U.S. Department of Labor Wage and Hour Division.
- Disability, pregnancy, or other discrimination/retaliation: file a charge with the EEOC (or your state's equivalent fair-employment agency).
- State or local paid sick leave violations: contact your state labor department or the local agency that enforces the ordinance.
- Safety-related retaliation: file with OSHA.
- Concerted-activity retaliation: file with the National Labor Relations Board.
Deadlines are real and can be short. For EEOC charges, you generally must file within 180 days of the adverse action, extended to 300 days in states with their own fair-employment agency. Other laws and state programs have their own clocks. Because missing a deadline can permanently end your claim, do not sit on it.
When to Talk to an Employment Lawyer
You do not need a lawyer to ask questions or file an agency complaint, but it is worth a conversation when real money or your job is on the line, when the situation involves disability, pregnancy, FMLA, or a contract, or when you simply are not sure whether your absence was protected. Many employment lawyers offer free initial consultations, and many handle retaliation and discrimination cases on a contingency basis, meaning they are paid only if you recover. Reaching out early is especially smart because of the strict filing deadlines, like the EEOC charge window, that can apply.
