How long you have to file a workplace grievance depends entirely on what kind of complaint it is and who your employer is. Union contracts can require filing in as few as five days. Employer handbooks often give a week to 30 days. Discrimination charges with the EEOC allow 180 days, extended to 300 in most states. Federal employees have just 45 days to start an EEO complaint. Unfair labor practice charges with the NLRB run six months. Miss whichever deadline applies, and your case is almost always over before it begins.
Union Contract Grievances
Collective bargaining agreements set some of the shortest filing windows in employment law. Some contracts give as few as five days after the incident. Others allow 20 or more. The exact number lives in your contract, and arbitrators enforce it strictly. If the language says 10 calendar days, day 11 is too late.
One trigger detail catches people off guard. In many union agreements, the clock starts when a steward or union officer learns about the problem, not when the affected employee first notices it. A steward who spots a contract violation during a routine walkthrough can start the deadline running even if no one has complained. That rule also cuts the other way: if no union representative knew about the issue, the deadline may not have started yet.
Non-Union Workplaces
If you’re not in a union, your employer’s handbook or internal HR policy controls the process. Deadlines vary widely — some companies give 30 days, others require you to raise concerns within a week. These internal deadlines are just as binding as union deadlines, even though no contract backs them up. Check your handbook or ask HR directly before you assume you have time.
EEOC Discrimination and Retaliation Charges
Discrimination complaints under federal law follow a separate track from any internal grievance procedure. You have 180 calendar days from the discriminatory act to file a charge with the Equal Employment Opportunity Commission, covering race, sex, disability, age, religion, and other protected categories.1U.S. Equal Employment Opportunity Commission. Time Limits for Filing a Charge
That window extends to 300 calendar days if a state or local agency enforces a similar anti-discrimination law, which is the situation in most states. Age discrimination follows a slightly stricter rule: the 300-day extension applies only when both a state law and a state enforcement agency exist. A local ordinance alone won’t extend the deadline.2U.S. Equal Employment Opportunity Commission. How to File a Charge of Employment Discrimination

Federal Employee Deadlines
Federal workers face much shorter windows. For discrimination complaints, you must contact your agency’s EEO counselor within 45 days of the discriminatory act.3U.S. Equal Employment Opportunity Commission. Overview of Federal Sector EEO Complaint Process Formal complaints and investigations follow, but missing that 45-day contact deadline can end your case at the start.
Federal employees also have to choose. If your union contract covers discrimination claims, you cannot pursue both the EEO process and the negotiated grievance procedure for the same incident.
For adverse personnel actions — removal, suspension of more than 14 days, or demotion — you can appeal to the Merit Systems Protection Board within 30 calendar days of the effective date or the date you receive the agency’s decision, whichever is later. If you and the agency agree to try alternative dispute resolution first, the window extends to 60 days.4U.S. Merit Systems Protection Board. Introduction to Federal Employee Appeals With MSPB
For day-to-day contract disputes, federal employees covered by a collective bargaining agreement use the negotiated grievance procedure. Federal law requires those procedures to be fair, simple, and prompt, but the actual step-by-step deadlines are set by each agency’s contract with its union.5U.S. Federal Labor Relations Authority. 5 U.S.C. 7121 – Grievance Procedures
OSHA and Whistleblower Complaints
OSHA enforces multiple whistleblower protection statutes, each with its own deadline. Filing windows run from 30 to 180 days depending on which law covers your situation.6Whistleblowers.gov. Tolling of Limitation Periods Under OSHA Whistleblower Laws The shortest — 30 days — applies to retaliation complaints under the core Occupational Safety and Health Act. Statutes covering aviation, nuclear energy, and financial services allow more time, but rarely more than 180 days.
NLRB Unfair Labor Practice Charges
Some union-related disputes go beyond internal grievance procedures. If an employer interferes with organizing rights, or a union fails to fairly represent its members, the complaint falls under federal labor law. You have six months from the date of the unfair labor practice to file a charge with the National Labor Relations Board.7Office of the Law Revision Counsel. 29 U.S. Code 160 – Prevention of Unfair Labor Practices That six-month window is a hard statutory deadline and applies regardless of what your union contract says about internal timelines.
How the Clock Starts and How Days Are Counted
The filing period usually begins on the date of the incident. But many grievance systems apply a “knew or should have known” standard. The clock starts when you discovered the problem, or when a reasonable person in your position would have discovered it. If the violation was hidden — say, a pay discrepancy buried in your records — the deadline may not begin until you had a realistic chance to find it. Ignoring an obvious warning sign won’t buy you more time.
When counting your filing period, exclude the day of the incident itself. The first day you count is the day after the triggering event, and that is standard practice across federal courts and most administrative proceedings.8Office of the Law Revision Counsel. Federal Rules of Civil Procedure Rule 6 – Time
Whether the count runs in calendar days or business days makes a real difference. EEOC deadlines run in calendar days. Union contracts may specify either. A “10-day” deadline could mean 10 business days (two full work weeks) or 10 calendar days (a week and a half). Read the exact language in the governing document.
When a Deadline Can Be Extended
Filing deadlines feel absolute, but a few doctrines can extend them in limited circumstances. The exceptions are narrow. Counting on them is a gamble.
Equitable Tolling
Courts can pause the clock when someone has been actively pursuing their rights but an extraordinary circumstance prevented timely filing. You have to show two things: reasonable diligence on your part, and an exceptional barrier that stood in your way. Forgetting, being busy, or not knowing the rules doesn’t qualify. Courts have accepted things like an employer actively concealing a violation, or the filer being physically incapacitated.
Continuing Violations
When discriminatory conduct isn’t a single incident but an ongoing pattern, each new act can restart the filing clock. The EEOC recognizes that a complainant may pursue a timely claim for ongoing discrimination that continues into the filing period, even if earlier events in the same pattern fell outside the original deadline.9U.S. Equal Employment Opportunity Commission. The Digest of Equal Employment Opportunity Law This applies to patterns of behavior, not isolated incidents that happen to share a theme.
Waiver by the Other Side
In union grievance procedures, an employer who processes a grievance on its merits without raising a timeliness objection may waive the right to argue later that the filing was late. The objection has to be clear and prompt. Participating in the meetings and arguing the substance can be treated as accepting the filing’s timeliness. The rule cuts both ways: unions can lose the right to object to employer deadlines through their own conduct.
What Happens If You Miss the Deadline
Your grievance will almost certainly be rejected. In a union setting, the employer can refuse to process it, and an arbitrator will likely dismiss it as untimely. The EEOC will dismiss a charge filed after the deadline unless you can demonstrate grounds for tolling. The MSPB applies its filing deadlines strictly.
The damage goes beyond the single complaint. A dismissed grievance often means the employer’s action stands unchallenged, which can make future grievances on the same issue harder to pursue. If you realize you’ve already missed a deadline, file immediately anyway and argue for an exception. A late filing has a slim chance. No filing has none.
Filing Before the Deadline Runs
Write down every relevant date, the names of people involved, and the specific policy or contract provision that was violated. Collect emails, text messages, photos, witness names, and any documents that support your account. Your written grievance should describe what happened, when it happened, what rule was broken, and what you want done. Point to a specific contract article or policy provision if you can; vague complaints about unfairness are easy to dismiss.
File through whatever method your policy requires — hand delivery, certified mail, email, or an online portal. In most systems, the grievance must be received by the deadline, not just sent. Don’t wait until the last day to drop an envelope in the mail. Get proof of submission: a signed receipt, an email confirmation, or a screenshot of an online submission page. Certified mail with return receipt requested is the safest option when timing is tight. Keep copies of everything, note when you should expect a response, and follow up in writing if that date passes.
