Fired Before Your Pension Vested or to Cut Benefit Costs? ERISA Section 510 Rights
ERISA Section 510 bars firing or disciplining a worker to interfere with pension, 401(k), or health plan benefits. Learn the rules, evidence, and limits.
What ERISA Section 510 Prohibits
Section 510 of the Employee Retirement Income Security Act, codified at 29 U.S.C. 1140, makes it unlawful for any person to discharge, fine, suspend, expel, discipline, or discriminate against a plan participant or beneficiary for exercising a right under an employee benefit plan or ERISA, or for the purpose of interfering with the attainment of any right the participant may become entitled to under the plan. It also protects a person who has given information or testified, or is about to testify, in an inquiry or proceeding relating to ERISA. In plain terms, an employer generally cannot fire or punish a worker in order to keep that worker from earning or using covered plan benefits, or because the worker used them.
Which Benefits Are Covered
ERISA generally covers private-sector employee benefit plans, including pension plans such as traditional defined benefit plans and 401(k)-type individual account plans, and welfare plans such as employer-sponsored health, disability, and life insurance plans. Government employer plans and church plans are generally outside ERISA, so different rules may apply to those workers. In Inter-Modal Rail Employees Assn. v. Atchison, Topeka & Santa Fe Railway Co., the Supreme Court held that Section 510 is not limited to rights that can vest. Its reference to any right under a plan includes welfare benefit plans, such as health benefits, even though those benefits are not subject to ERISA's vesting rules.
Vesting Schedules and Why Timing Matters
Vesting is the point at which your right to employer-funded retirement benefits becomes nonforfeitable. Under 29 U.S.C. 1053, your own contributions are always vested. For employer contributions, a 401(k)-type individual account plan must vest them at least as fast as either 100 percent after 3 years of service or a graded schedule that starts at 20 percent after 2 years and reaches 100 percent after 6 years. A defined benefit pension must vest at least as fast as 100 percent after 5 years or a graded schedule that starts at 20 percent after 3 years and reaches 100 percent after 7 years. Plans can vest faster, so check your own plan's summary plan description. A termination shortly before a vesting date, an early retirement eligibility date, or a benefit milestone can be evidence worth examining.
Proving the Employer's Purpose
Section 510 turns on the employer's purpose. Losing benefits as a side effect of a termination is not enough by itself; the claim is that the employer specifically intended to interfere with plan rights when making the decision. An employer can generally change or end a welfare plan through the plan's formal amendment process; Section 510 targets using discharge or discipline against particular participants to interfere with their plan rights. Courts differ on exactly how this intent must be shown, but evidence that can matter includes how close the firing was to a vesting date or large benefit claim, statements about benefit costs, pension liabilities, or expensive health claims, a pattern of terminating workers near the same milestone, shifting explanations for the decision, and a strong performance history before the termination. The employer will usually point to another reason, such as performance, restructuring, or cost cutting unrelated to plan rights, so documents showing what decision-makers knew and when they knew it are important.
Using Health or Disability Benefits Can Be Protected Too
Section 510 also covers discrimination for exercising a right under a plan. A firing or discipline that follows a large health insurance claim, a request for plan disability benefits, or a question to the plan administrator about your benefits can raise a Section 510 issue, depending on the facts. The same events may also involve other laws. A serious medical condition can bring the Americans with Disabilities Act or the Family and Medical Leave Act into play, and those laws have their own deadlines and filing routes.
How Section 510 Relates to Age Discrimination
Pension timing is often tied to years of service, which tends to track age. In Hazen Paper Co. v. Biggins, the Supreme Court held that firing an older worker to prevent pension vesting based on years of service is not, by itself, age discrimination under the Age Discrimination in Employment Act, because years of service is analytically distinct from age. The Court noted that this does not rule out liability under both ERISA and the ADEA, liability where pension status is used as a proxy for age, or liability where vesting is based on age. If age also played a role, an ADEA charge with the EEOC generally must be filed within 180 days, or 300 days if a state law prohibits age discrimination in employment and a state agency enforces it; a local law alone does not extend the ADEA deadline.
How These Claims Are Brought
Section 510 is enforced through ERISA's civil enforcement provision, 29 U.S.C. 1132. A participant may sue to stop a violation or to obtain other appropriate equitable relief, and federal district courts have exclusive jurisdiction over those claims. The court may, in its discretion, award reasonable attorney's fees and costs to either party. In Ingersoll-Rand Co. v. McClendon, the Supreme Court held that a state-law wrongful discharge claim alleging that an employer fired a worker to avoid pension contributions was preempted, and that ERISA's civil enforcement provision is the exclusive remedy for that claim. The types of monetary relief available as equitable relief, whether plan claim procedures must be used first, and the applicable filing deadline can differ by court. ERISA does not set a specific filing deadline for Section 510 claims, so courts often borrow one from state law, and that period may be short.
Getting Plan Documents
Under 29 U.S.C. 1024(b)(4), a plan administrator must, on a participant's written request, furnish copies of the latest summary plan description, the latest annual report, and the instruments under which the plan is established or operated, and may charge a reasonable copying fee. If an administrator fails to comply within 30 days without a reason beyond its control, 29 U.S.C. 1132(c) allows a court, in its discretion, to impose a daily penalty. Make the request in writing, keep a copy, and note the date it was sent. Pension benefit statements typically show your service credit and vested status.
Records to Save
Save your offer letter, hire date records, benefit enrollment confirmations, summary plan descriptions, benefit and vesting statements, recent performance reviews, the termination letter, and any severance or release documents. Write down dates of any large benefit claims, leave requests, or benefit questions and who knew about them. Keep messages that mention benefit costs, pension liabilities, headcount near vesting dates, or insurance premiums, based on information you lawfully have. Do not take confidential employer or plan records you are not authorized to keep; describe them so a lawyer can request them.
Before Signing a Severance Release
Severance agreements often include a release of claims, which may include ERISA claims such as a Section 510 claim. Read the release language, check whether it mentions benefit plans, and ask the plan for your vested balance before signing. Workers 40 or older have additional protections when a release waives age discrimination claims, under the Older Workers Benefit Protection Act, including a period to consider the agreement and a period to revoke it after signing.
When to Get a Free Consult
Get a free consult if you were fired or pushed out shortly before a vesting date, early retirement eligibility, or another benefit milestone, or soon after filing a large health or disability benefit claim, especially if benefit costs were mentioned or your prior reviews were positive. Deadlines may be short, so act promptly. This article is general information, not legal advice.
