An employment contract is an agreement that sets the terms of a job. In the US most hourly jobs have no written contract, which means the default rules of at-will employment and state law fill the gaps.
| Type | What it looks like | Typical roles |
|---|---|---|
| Written, fixed-term or for cause | A signed agreement with a term, termination rules and pay | Executives, specialized hires, some healthcare and education roles |
| Offer letter with at-will language | A letter that states pay and start date and says employment is at will | Most hourly and salaried staff |
| Implied contract | Promises in a handbook, letter or conversation that a court may treat as binding | Any role, often by accident |
| Collective bargaining agreement | A union contract covering a whole unit | Unionized workplaces |
Montana is the main exception to the at-will default. Its Wrongful Discharge from Employment Act makes a discharge wrongful if it was not for good cause and the employee had completed the employer’s probationary period. Everywhere else, at will is the starting point unless a contract or law says otherwise. See at-will employment.

A small security company’s handbook says: “After 90 days, employees will only be terminated for just cause after three written warnings.” The offer letters say employment is at will. Two years later, a guard is let go after one serious incident and argues that the handbook promised three warnings.
Whether that sentence creates an implied contract depends on the state and the exact wording, but the company has handed the guard an argument. The fix is cheap: the handbook should describe discipline steps as typical, not guaranteed, keep a clear at-will statement, and have employees sign an acknowledgment that says the handbook is not a contract.
A written contract is still useful when you do want to promise something, such as a fixed term for a key hire or a notice period. Then write exactly what you mean, including how either side can end it early.
A ski resort hires a lift supervisor for the season from December 1 to April 15 with a written agreement. It says the job ends on April 15, that either side can end it early with two weeks’ notice, and that a completion bonus is paid if he works through the last day.
When the season ends early because of poor snow on March 31, the resort gives the two weeks’ notice the agreement requires and pays according to the agreement’s terms. Because every point was written down, there is no argument about what was owed.
Most do not have a formal written contract. They have an offer letter and a handbook, and employment is at will. Written contracts are more common for senior, specialized or unionized roles.
It can create contractual obligations, depending on its wording. Most offer letters state that employment is at will to avoid creating a fixed-term contract. See the job offer letter template.
The employee may be able to claim damages, such as pay for the rest of a fixed term. Remedies depend on the contract and state law.
Yes. A contract can confirm at-will status while setting out pay, duties and confidentiality. It only changes the at-will default if it promises a fixed term or termination only for cause.
Yes, if you intend to promise anything beyond at-will employment. Spoken promises can still create obligations and are much harder to prove.
A contract with fixed terms generally needs both sides to agree to a change. At-will policies can usually be changed going forward with notice.
