Offer Letter Red Flags: 6 Clauses to Catch Before You Sign

You got the offer on a Friday. The HR team wants the signed copy back Monday. The letter is four pages and the appendices behind the paperclip are seventeen. Almost everything that will matter to your life at this company over the next four years is in those seventeen pages, and almost none of it is in the four pages they walked you through on the call.

A modern offer letter is a stack of contracts pretending to be a single document. The first page is the headline (title, salary, start date). The pages behind it are the at-will acknowledgment, the arbitration agreement, the proprietary information and inventions assignment, the restrictive covenant addendum, the equity grant terms, the signing bonus repayment agreement, and a release of claims for anything that happened during the interview. Each one is its own contract. Each one is enforceable. The recruiter who walked you through the salary number does not know what's in most of them, and is not authorized to negotiate any of them.

The six red flags below are the ones that come up most often in employment-law forums and that the FTC, state attorneys general, and state legislatures have been moving against in the last twelve months. Each of them has been in the news in 2025 or 2026. Each of them is in your offer right now if you're about to sign.

TL;DR

• The six highest-leverage offer letter red flags are the mandatory arbitration clause, the inventions assignment, the signing bonus clawback, the non-compete restrictive covenant, the discretionary bonus language, and the equity vesting and exercise window.
• Severity tiers: High risk clauses change where you fight or what you owe if you leave. Medium risk clauses change how much you actually take home compared to the headline.
• The FTC's non-compete ban is dead. The Commission voted 3-1 to abandon its appeal in September 2025. State law is now the only restriction on non-competes for most workers.
• California's AB 692 (effective January 1, 2026) and New York's "Trapped at Work Act" (effective December 19, 2025) sharply limit signing bonus clawbacks in those two states. Outside them, the clawback you signed is almost always enforceable.

1. The arbitration clause that decides where you fight

High risk

In the standard arbitration agreement appendix:

Any dispute, controversy, or claim arising out of or relating to
Employee's employment with Company, including statutory claims under
Title VII, the ADEA, the ADA, the FLSA, and any state-law equivalents,
shall be resolved exclusively by final and binding arbitration before
a single arbitrator administered by JAMS in accordance with its
Employment Arbitration Rules. Employee waives any right to participate
in a class, collective, or representative action.

In one paragraph you've given up jury trials, public court records, the right to appeal on the merits, and the right to join a class action with other employees who were treated the same way. The Supreme Court made class waivers enforceable in Epic Systems v. Lewis (2018). The Ending Forced Arbitration of Sexual Assault and Sexual Harassment Act of 2021 (signed March 2022) carves out sexual-assault and sexual-harassment claims, which means you can still sue in court for those even if you signed this. Everything else, you arbitrate.

The asymmetry is real. Arbitration costs the employer more per case than litigation, but the employer pays the arbitrator's fees and uses the same firm repeatedly. The arbitrator who rules against the employer too often does not get hired again. The data on win rates reflects this; employees prevail less often in arbitration than in court, and average awards are lower.

Push back: ask for the arbitration clause to carve out claims for unpaid wages, retaliation, and statutory whistleblower claims, or to require the employer to bear all arbitration costs (so the cost asymmetry doesn't deter you from filing). Some employers will agree. Most won't drop the clause entirely.

2. The inventions assignment that swallows your side projects

High risk

In the proprietary information and inventions assignment:

Employee hereby assigns to Company all right, title, and interest in
and to any and all inventions, original works of authorship,
developments, concepts, improvements, designs, discoveries, ideas,
trademarks, or trade secrets, whether or not patentable or registrable
under copyright or similar laws, that Employee may solely or jointly
conceive or develop or reduce to practice, or cause to be conceived
or developed or reduced to practice, during the period of
employment with Company.

Read literally, that clause says everything you create while employed at the company belongs to the company. Not just things you make at work. Not just things related to the company's business. Everything. The novel you write at night. The open-source project on your GitHub. The side consulting work for your friend's startup.

California limits this. Labor Code Section 2870 carves out inventions developed entirely on your own time, without using the employer's equipment or trade secrets, and that don't relate to the employer's business or to anything you were assigned at work. Eight other states (Delaware, Illinois, Kansas, Minnesota, North Carolina, Utah, Washington, and New Jersey via 2024 amendment) have similar carve-outs by statute. In the rest of the country, the clause is enforced as written.

Push back has two parts. First, ask for the assignment to be limited to inventions related to the company's business or made using company resources. Second, attach a "Schedule A" listing your prior inventions, side projects, and open-source contributions. Anything on Schedule A is excluded from the assignment by definition. The standard offer letter has a blank Schedule A. Most candidates leave it blank. Don't.

3. The signing bonus you might owe back

High risk

In the signing bonus repayment agreement:

Company will pay Employee a signing bonus of $25,000, payable within
30 days of the Start Date. If Employee voluntarily terminates
employment or is terminated for Cause within twenty-four (24) months
of the Start Date, Employee agrees to repay the full amount of the
signing bonus to Company within thirty (30) days of the date of
termination.

These are called "stay-or-pay" agreements. They turned a bonus into a loan. Most are enforceable in most states. Two big 2025-2026 changes you need to know:

California AB 692 (effective January 1, 2026) requires the repayment obligation to be in a separate written agreement, not the offer letter; requires the employer to notify the employee of the right to consult counsel and provide at least five days to do so before signing; requires the repayment amount to be prorated against the time served; and caps the retention period at two years.

New York's Trapped at Work Act (signed December 19, 2025, effective immediately) bars "employment promissory notes" but carves out signing bonus repayment. Critically, the carve-out does not apply if the employee is terminated for any reason other than misconduct, or if the employer misrepresented the requirements of the job. If you're laid off, you don't owe it back.

Find your state below. The status column tells you how much room you have to push back. Filter or sort.

Outside California, New York, and Connecticut, the standard pattern stands. Push back on three points: (1) trigger the clawback only on voluntary departure, not termination without cause; (2) prorate the repayment so leaving at month 18 means owing 25 percent, not 100 percent; (3) shorten the retention period to twelve months.

4. The non-compete the FTC didn't kill

High risk

In the restrictive covenant addendum:

For a period of twelve (12) months following the termination of
Employee's employment for any reason, Employee shall not directly or
indirectly engage in or be employed by any business that competes with
Company within the United States, nor solicit any employee, customer,
or business partner of Company.

In April 2024 the FTC issued a final rule that would have banned most post-employment non-competes nationwide. In August 2024 the Northern District of Texas vacated the rule. In September 2025 the FTC voted 3-1 to abandon its appeal in the Fifth Circuit. The federal ban is dead.

What remains is state law. California, Minnesota, North Dakota, and Oklahoma ban most non-competes by statute. Colorado, Illinois, Massachusetts, Maine, Oregon, Rhode Island, Virginia, and Washington restrict them sharply (income thresholds, notice periods, garden-leave requirements). The other thirty-seven states enforce non-competes if they meet a "reasonableness" test that varies by jurisdiction and judge.

Negotiate three things: (1) limit the scope to companies that genuinely compete (not "any business in the industry"); (2) limit the geography to where you actually worked (not "the United States"); (3) shorten the duration to six months and require the company to pay your salary during it (a "garden leave" structure, which is now mandatory in some states for higher earners). For the longer treatment, see the non-compete clause guide, which walks state by state.

5. The "discretionary" bonus that isn't really yours

Medium risk

In the compensation summary section:

Employee will be eligible to participate in Company's discretionary
annual bonus program, with a target bonus of 20% of annual base
salary. Bonuses are awarded at the sole discretion of Company and
are not earned until paid. Employee must be employed by Company on
the date bonuses are paid to receive any bonus.

The recruiter quoted $200,000 base plus 20 percent target bonus, "so $240,000 all-in." The clause says the bonus is discretionary, not earned until paid, and forfeited if you're not employed on the payout date (typically March of the following year). Three things make the bonus number unreliable: (1) "discretionary" means the company can pay zero with no breach; (2) "not earned until paid" defeats most state-law arguments that you were entitled to the unpaid bonus; (3) the must-be-employed rule lets the company let you go in February and pay you nothing.

Push back: ask for the bonus to be "based on objective, written performance criteria"; ask for the prorated bonus to be paid on departure; ask for the must-be-employed rule to apply only to voluntary departures. The last one alone is worth tens of thousands at higher levels.

6. The equity vesting cliff and the 90-day exercise window

Medium risk

In the equity grant terms:

The shares subject to the Option shall vest over a four (4) year
period, with twenty-five percent (25%) vesting on the first
anniversary of the Vesting Commencement Date (the "Cliff Date") and
the remainder vesting in equal monthly installments thereafter.
Vested options must be exercised within ninety (90) days of
termination of Employment or they shall be forfeited.

Two traps. First, the one-year cliff. If you leave at month eleven, you get nothing. Even if the company misled you about the role and you're leaving because of that, you forfeit everything. Second, the 90-day post-termination exercise window. If your equity is in incentive stock options (ISOs) and you have $400,000 of paper gains, exercising in 90 days means writing a check for the strike price plus a tax bill on the spread. Many employees leave and walk away from vested equity because they can't afford to exercise.

Modern employee-friendly equity plans extend the post-termination exercise window to seven or ten years. Coinbase, Pinterest, Shopify, and a growing list of late-stage privates have done this. Ask. If the answer is no, factor it into the offer; the equity is worth less than the company's strike-price math says.

For acceleration on change-of-control, ask for "double-trigger" vesting (acceleration only if the company is acquired AND you're terminated without cause within twelve months). Single-trigger acceleration is rare and usually reserved for executives.

How to push back without losing the offer

The recruiter does not own these clauses. The hiring manager does not own these clauses. The general counsel owns these clauses, and the general counsel has seen every standard pushback. The pattern that works:

1. Send written redlines, one document at a time. A single email with marked-up arbitration, IP assignment, and clawback language is faster to handle than a phone call.
2. Anchor to your strongest specific. "I have prior open-source contributions on Schedule A" beats "I want to negotiate the IP clause." Specific is harder to reject.
3. Pick three. Drop the rest. Most candidates ask for everything and get nothing. The candidate who asks for one carve-out, one clawback adjustment, and one bonus protection gets two of the three more often than not.
4. Get every promise in writing in the offer letter. If the recruiter says "we always pay the discretionary bonus at target," ask for that to be reflected in the bonus clause. If they won't put it in writing, it isn't true.

The six flags above are six different shapes of the same pattern: a contract where the headline number is the easiest part to negotiate and the structural risks are written to be hard to find. That's the shifted risk shape from the contract red flags playbook, in a single document. The same shape runs through the indemnification clause you'll see in your next vendor contract and the payment terms you'll see if you go independent.
