A collective bargaining agreement changes wages and severance by turning them into contract rights: your pay follows a negotiated scale that the employer cannot cut mid-contract, your overtime is calculated on a regular rate that includes CBA shift differentials, and severance becomes a legal obligation triggered by specific events rather than a discretionary goodbye check. The trade-off is that you enforce those rights through the contract’s grievance procedure, on deadlines that are shorter than most workers expect.
How a CBA Sets Your Wages
Once a CBA is in place, your pay comes from the contract’s wage schedule rather than a manager’s judgment of what you are worth. Schedules sort compensation into job classifications and seniority tiers, so two workers with the same title and years of service earn the same base rate. You move through the tiers on a predictable timeline, with raises tied to longevity rather than performance reviews. Many contracts also include cost-of-living adjustments that lift pay automatically based on the Consumer Price Index.
This structure exists because federal law gives your union exclusive authority to negotiate wages for everyone in the bargaining unit. Under the National Labor Relations Act, a union chosen by a majority is the sole representative for all employees in that unit on pay, hours, and working conditions.1Office of the Law Revision Counsel. 29 USC 159 – Representatives and Elections Your employer cannot cut a side deal with you for higher or lower pay outside the contract, and you cannot individually negotiate a raise above the scale either. When an employer offers merit pay or bonuses that the agreement does not authorize, the National Labor Relations Board treats the change as an unfair labor practice.2National Labor Relations Board. Bargaining in Good Faith With Employees Union Representative
The contract nature of these rates also means they cannot be reduced during the life of the agreement without the union’s consent.2National Labor Relations Board. Bargaining in Good Faith With Employees Union Representative You can project your earnings years ahead. The employer is locked into those costs regardless of how the business performs.
Dues Deductions From Your Paycheck
Most CBAs include a dues checkoff that lets the employer deduct union membership fees directly from your wages. Federal law requires your written authorization before any deduction can happen, and that authorization cannot be made irrevocable for longer than one year or the remaining life of the contract, whichever comes first.3Office of the Law Revision Counsel. 29 USC 186 – Restrictions on Financial Transactions If you never signed that authorization, dues cannot legally be withheld from your pay.
How CBA Premiums Change Your Overtime Rate
Shift differentials and premium pay negotiated in your CBA affect the overtime calculation in ways many workers overlook. Under the Fair Labor Standards Act, the regular rate used to calculate overtime at time-and-a-half must include all compensation for hours worked, including shift differentials.4U.S. Department of Labor. Fact Sheet 56A – Overview of the Regular Rate of Pay Under the Fair Labor Standards Act If your base rate is $30 per hour and you get a $3 night-shift differential, your overtime rate is based on $33, not $30.
There is an important exception. Premium pay that your CBA provides for work beyond the normal workday or workweek can be excluded from the regular rate and credited toward overtime obligations, but only if the premium is at least one-and-a-half times your base rate for similar work during regular hours.5Office of the Law Revision Counsel. 29 USC 207 – Maximum Hours A CBA that pays double-time for Sunday work can credit that premium against the federal overtime requirement. A CBA that pays only a flat $2 extra for Sundays cannot. Miscalculating the regular rate is one of the most common payroll errors in unionized workplaces, and back pay adds up quickly when it applies to an entire bargaining unit.
When Prevailing Wage Pushes CBA Pay Higher
If you work on a federally funded construction project worth more than $2,000, the Davis-Bacon Act requires your employer to pay at least the prevailing wage for your trade in the area where the project is located.6Office of the Law Revision Counsel. 40 USC 3142 – Rate of Wages for Laborers and Mechanics Prevailing wage is not just an hourly rate. It also covers fringe benefits like health insurance, pension, and apprenticeship fund contributions.7U.S. Department of Labor. The Davis-Bacon Act, as Amended
The connection to CBAs is direct. When the Department of Labor surveys wages to set prevailing rates for an area, union-negotiated rates often represent the majority of the data, and the CBA rate becomes the prevailing wage for that classification.8U.S. Department of Labor. Davis-Bacon Wage Determinations Where no single union rate dominates, the department uses a weighted average of union and non-union wages.
What this means for your paycheck: if the Department of Labor updates a prevailing wage determination and the new rate exceeds what your CBA currently provides, your employer must pay the higher amount on that project. The CBA sets a floor. Prevailing wage law can push your actual pay above that floor on government work.
Severance as a Contract Right
Most American workers have no legal right to severance pay. A CBA changes that by making severance a contractual entitlement the employer must honor whether it feels generous or not. These provisions spell out the triggers, with permanent layoffs, plant closings, and displacement by automation being the most common.
The calculation formula is usually one or two weeks of pay for each year of completed service. A worker with 15 years on the job under a two-week-per-year formula receives 30 weeks of pay. The numbers are negotiated in advance and cannot be reduced when the layoff actually happens. Many agreements also require the employer to continue health insurance contributions for a set number of months after separation, which can be worth thousands of dollars on top of the cash payment.
Because the severance obligation is written into the contract, an employer cannot legally condition the money on you signing a release of claims. A release waives your right to sue over other potential violations, and while employers routinely require releases for discretionary severance, a CBA-mandated payment is already owed. If the employer offers additional severance beyond what the contract requires, it can condition that extra amount on a release. The distinction between what the contract guarantees and what the employer volunteers matters when you are under pressure to sign documents during a layoff.
Plant Closings and the WARN Act
When a CBA severance provision is triggered by a plant closing or mass layoff, the Worker Adjustment and Retraining Notification Act adds another layer. Employers with 100 or more full-time workers must provide 60 days’ written notice before shutting down a facility or conducting a large-scale layoff.9Office of the Law Revision Counsel. 29 USC 2102 – Notice Required Before Plant Closings and Mass Layoffs Notice must go to the union representing affected employees, the state rapid-response agency, and local government officials.
An employer that skips the notice owes each affected worker back pay and benefits for every day of the violation, up to a maximum of 60 days.10Office of the Law Revision Counsel. 29 USC 2104 – Administration and Enforcement of Requirements That liability runs on top of whatever severance the CBA already requires. Many CBAs incorporate WARN compliance by reference or add notice requirements that exceed the federal minimum.
If Your Employer Files for Bankruptcy
If your employer files for bankruptcy before paying your severance, the Bankruptcy Code gives wage and severance claims priority over most other unsecured creditors. Each worker can claim up to $17,150 for wages, severance, and similar compensation earned within 180 days before the bankruptcy filing or the shutdown date, whichever came first.11Office of the Law Revision Counsel. 11 USC 507 – Priorities Priority does not guarantee full payment if the company’s assets fall short, but it puts you ahead of trade creditors, landlords, and general unsecured debt in the distribution line.
What Happens If the Business Is Sold
A change in ownership does not automatically preserve your CBA wage scale. Under the Supreme Court’s decision in NLRB v. Burns International Security Services, a successor employer that hires a majority of the predecessor’s workforce must recognize and bargain with the incumbent union, but it is not required to adopt the predecessor’s contract terms.12Justia. NLRB v. Burns International Security Services, Inc., 406 US 272 (1972) The new owner can set its own initial pay rates, even below the old CBA, so long as it bargains in good faith going forward.
Successorship clauses are the counterweight. Many CBAs require the current employer to make any sale or transfer conditional on the buyer assuming the existing contract. Arbitrators have enforced these clauses against acquiring companies when the language is clear, binding the new owner to the old wage scale for the remaining life of the agreement, and courts give heavy deference to arbitrators interpreting them. If your CBA lacks a successorship clause, that gap is worth raising during the next round of negotiations.
Taxes on Severance and Back Pay
Severance recovered under a CBA is treated as wages for federal tax purposes. Your employer must withhold income tax and FICA just as it would from a regular paycheck, and the payment appears on your W-2.13Internal Revenue Service. Tax Implications of Settlements and Judgments If the payment qualifies as supplemental wages and the employer does not combine it with your regular pay, it may be withheld at a flat 22% rate for federal income tax.14Internal Revenue Service. Publication 15-A (2026), Employers Supplemental Tax Guide
Back pay follows the same logic. Whether you recover unpaid wages through arbitration or a settlement, the IRS treats the whole amount as income in the year you receive it, not the years you should have been paid.15Internal Revenue Service. Publication 525, Taxable and Nontaxable Income A lump-sum award can push you into a higher bracket for that year. There is no mechanism to spread the liability back over the years the pay was originally owed, so a worker who wins three years of back pay in arbitration faces a potentially painful tax bill.
Enforcing Wage and Severance Terms
When your employer shortchanges you on wages or severance the CBA guarantees, the contract’s grievance procedure is your first and usually only path to a remedy. Federal law requires you to exhaust every step of that internal process before going to court. That typically means filing a written grievance, attending formal meetings between union representatives and management at escalating levels, and submitting the dispute to a neutral arbitrator if it cannot be resolved informally.
The legal foundation is Section 301 of the Labor Management Relations Act, which gives federal courts jurisdiction over CBA breach claims but routes them through the contract’s own dispute resolution machinery first.16Office of the Law Revision Counsel. 29 USC 185 – Suits by and Against Labor Organizations An arbitrator’s decision on a wage grievance is binding and enforceable in court. Most arbitrators have broad authority to order back pay, and some will award interest on unpaid amounts when the contract does not explicitly prohibit it, though there is a genuine split on that question.
When the Union Fails You
Your union handles the grievance on your behalf, which raises the obvious concern about a union that does a bad job. Federal law imposes a duty of fair representation: the union cannot process your grievance in a way that is arbitrary, discriminatory, or in bad faith.17Justia. Vaca v. Sipes, 386 US 171 (1967) The bar for proving a breach is high. A union does not violate this duty just because it settles your grievance for less than you wanted or decides the claim is not worth arbitrating. You need to show the union’s conduct was genuinely unreasonable or motivated by hostility toward you.
If the union does breach its duty, you can bypass the exhaustion requirement and bring a hybrid claim in federal court against both the employer for the contract violation and the union for failing to represent you fairly. The same exception applies when the employer flat-out refuses to participate in the grievance process at all.
The Six-Month Deadline
The statute of limitations for these hybrid claims is six months, borrowed from the deadline for filing unfair labor practice charges with the National Labor Relations Board.18Legal Information Institute. DelCostello v. International Brotherhood of Teamsters, 462 US 151 (1983) That clock starts when you knew or should have known the union was not going to pursue your grievance, or when the final step of the grievance process produces an unfavorable result. Six months is brutally short compared to most civil statutes of limitations, and it catches workers off guard constantly.
For straight unfair labor practice charges filed with the NLRB, such as when an employer unilaterally cuts wages in violation of the CBA, the same six-month window applies from the date of the violation.19Office of the Law Revision Counsel. 29 USC 160 – Prevention of Unfair Labor Practices If you suspect your employer has changed a term of your contract without the union’s agreement, do not wait to see how it plays out. File the charge first and sort out the details later. A late charge is a dead charge, regardless of how strong the underlying claim would have been.
