Vesting, cliffs, and forfeiture: employment-money vocabulary

Job offers and exit paperwork are written in a vocabulary that determines tens of thousands of dollars — yet most people skim it. Whether you're negotiating an offer, weighing a job switch, or getting laid off, these are the terms that move money.

Vesting: when promised money becomes yours

Vesting is the schedule by which employer-granted money — 401(k) matches, stock grants, sometimes bonuses — converts from a promise into property you keep even if you leave. Until it vests, it can vanish.

• Cliff vesting — nothing vests until a set date, then a chunk vests all at once. A "1-year cliff" on a stock grant means quitting at month 11 forfeits everything.
• Graded vesting — ownership accrues in installments, like 20% per year over 5 years, or monthly after an initial cliff.
• Immediate vesting — it's yours the moment it's granted. Your own 401(k) contributions are always immediately vested; only employer money has a schedule.
• Accelerated vesting — a contract clause that vests equity early upon an event like an acquisition ("single-trigger") or acquisition plus termination ("double-trigger").
• Forfeiture — losing unvested money when you leave. Not a penalty, just the schedule doing what it says.

Equity compensation decoded

• RSU (Restricted Stock Unit) — a promise of company shares delivered when they vest. Taxed as ordinary income at vest based on that day's share price, like a cash bonus paid in stock.
• Stock option — the right to buy shares at a fixed "strike price." Valuable only if the stock rises above the strike. Common at startups.
• ISO vs NSO — two tax flavors of options. ISOs can get capital-gains treatment if you follow holding rules (but can trigger AMT); NSOs are taxed as income at exercise.
• ESPP (Employee Stock Purchase Plan) — buy company stock at a discount, typically 15%, through payroll deductions. A 15% discount with a lookback provision is often near-free money if you sell promptly.
• 83(b) election — a 30-day-deadline tax filing for early-exercised startup equity that can save enormous taxes. Miss the window and it's gone forever.
• Exercise window — how long you have after leaving to buy your vested options. Often just 90 days at startups, which can force a big cash-and-tax decision right when you lose a paycheck.

Leaving a job: the exit vocabulary

• Severance — pay offered when you're let go, commonly 1–2 weeks per year of service. It's a negotiation, not an entitlement, in most states.
• Separation agreement — the contract you sign to receive severance, usually waiving your right to sue. You're typically given 21 days (45 in group layoffs) to consider it if you're over 40.
• Garden leave / notice period — you've resigned or been terminated but stay on payroll (and off the job) for a defined stretch.
• Non-compete — a clause restricting where you work next. Enforceability varies dramatically by state — California voids most of them.
• Clawback — a provision letting the employer take back paid bonuses or relocation money if you leave within a set period. A $10,000 signing bonus with a 12-month clawback is a loan until month 13.
• COBRA — your right to keep employer health insurance up to 18 months after leaving, paying the full premium (often $600–800/month for an individual, $1,800+ for families).

Before you sign or resign: a checklist

1. Pull your 401(k) vesting schedule from the plan portal and note the exact date you hit 100%.
2. List every equity tranche and its vest date. If a vest lands within 90 days, price out what waiting is worth.
3. Check bonus timing — many companies require you to be employed on the payment date to receive an already-earned annual bonus.
4. Reread your signing bonus and relocation clawback windows.
5. If you hold stock options, confirm your post-termination exercise window and estimate the cash and tax cost of exercising.
6. Compare COBRA costs against a marketplace (ACA) plan before your coverage end date.

What a job switch really costs: the full tally

Run that table before accepting any offer and the negotiation changes shape. Suppose a recruiter offers you a $15,000 raise to move in October — but your current job pays a $12,000 bonus in March for work you have mostly finished, your next RSU tranche of $10,000 vests in January, and your 401(k) match hits its cliff in February. Leaving in October costs roughly $25,000 of nearly-earned money to collect a raise worth $15,000 in year one. The professional move is not declining; it is countering with a start date after the vest dates, or asking the new employer to make you whole with a signing bonus — a request so routine that large companies have a form for it.

The reverse also matters: employers design these schedules precisely because they work as retention. Golden handcuffs is the informal term for compensation structured so that leaving always forfeits something — overlapping RSU grants ensure there is never a clean exit date. The counter-vocabulary is simple bookkeeping: keep a one-page inventory of every unvested dollar and its date, update it at each grant, and reread it before any career conversation. People negotiate hardest over base salary, the most visible number, while the schedule-attached money quietly decides whether a move is profitable at all.

The bottom line

Employment money comes in two kinds: what's yours, and what's still a promise. Vesting schedules, cliffs, clawbacks, and exercise windows are the rules that convert one into the other — and they reward people who read the calendar. Before any job change, tally your unvested balances and their dates. Sometimes the most profitable career move is waiting six more weeks.
