Picking the perfect candidate is just one of many critical steps employers must take.

Once you’ve found the right person, selecting the proper employment contract is crucial, as this choice impacts both the employer and the employee.

A solid contract not only outlines the working relationship, rights, and obligations of the parties; it's a legal document that protects everyone involved over the course of employment.

Let's begin by defining what a contract is and how it can be offered.

The Ultimate Employee Onboarding Checklist

What is an employment contract?

An employment contract is a formal legal agreement that establishes the terms of your work relationship with an organization. It's a key legal document, often drafted by professionals, that specifies the conditions of employment and the responsibilities of each party.

A good contract should specify:

  • Basic Information: The names of both the employer and employee.
  • Compensation: Details on wages, bonuses, and commissions.
  • Working Schedule: Expected hours per week, location, and reporting structure.
  • Duration of Employment: Whether it's a fixed term or indefinite.
  • Benefits: Eligibility for medical insurance, retirement plans, paid time off (PTO), and sick leave.
  • Protections & Clauses: Such as confidentiality, non-compete, non-disclosure, and intellectual property ownership.
  • Conflict Resolution: The protocol for resolving disputes.
  • Termination Policy: The conditions and procedures for ending the employment relationship.

The Three Primary Forms of Employment Contracts

While we often think of contracts as formal documents, they can be established in a few different ways. All three are legally binding to some extent, but they differ in formality, purpose, and legal protection.

Written Contract

This is the most common form and is considered the "gold standard" in the contemporary business world.

A written contract explicitly details the employment relationship and is signed by both parties, providing clear and legally binding terms that are easy to enforce.

Verbal Contract

A verbal or oral contract is an agreement made through spoken words rather than written documentation.

While legally binding if they include the basic elements of an agreement, they are difficult to prove and enforce.

This lack of clarity can easily lead to misunderstandings and disputes.

Implied Contract

This is an unwritten and unspoken agreement inferred from actions, statements, and policies rather than explicitly stated.

For example, if your company policy only fires people who have made three fouls, but you fire someone after just one, this could be considered a breach of an implied contract.

Key Benefits of a Written Employment Contract

From legal protection to simplified dispute resolution, there are many important benefits to using employment contracts, especially written ones.

1. Ensures Legal Compliance

A clear contract makes it easier for employers to demonstrate and maintain legal compliance with federal, state, and local employment laws, including the Fair Labor Standards Act (FLSA) and Family and Medical Leave Act (FMLA).

By including anti-discrimination and equal treatment policies, contracts align with standards set by the Equal Employment Opportunity Commission (EEOC), which reduces the risk of discrimination claims.

2. Sets Clear Role Expectations

A contract that includes a clear and concise description of the employee's role, key duties, and reporting structure helps reduce misunderstandings and ensure accountability.

By outlining what is expected, you can improve both morale and job performance.

3. Enhances the Employer-Employee Relationship

By formalizing the terms of employment in writing, both parties clearly understand their obligations and rights.

This helps create an equitable workplace where employees feel valued and employers gain a clear framework for managing and addressing issues.

4. Simplifies Dispute Resolution

Workplace disputes can happen, but resolving them is much easier when a valid employment contract is in force.

The contract serves as an objective reference point, reducing ambiguity and making dispute resolution more straightforward.

Here are some of the most common types of employment contracts, each with its own purpose and legal standing.

1. Permanent Contract: Full-Time and Part-Time

A permanent employment contract, also known as an open-ended contract, is a long-term agreement where the employee is hired indefinitely. These are the most common contracts and form the backbone of a stable workforce.

  • When to Use: For roles that are core to your business operations. A permanent contract is a popular option for workers seeking job security and career growth.
  • Duration: No end date. The employment relationship continues until either party terminates it. In the U.S., most of these contracts fall under "at-will" employment, meaning either party can end the contract at any time, for any legal reason.
  • Pay and Benefits: The employee receives a regular, fixed salary or a set hourly rate. They are often entitled to a full range of benefits such as health insurance, retirement contributions, and paid time off that may not be available to temporary workers.
  • Drawbacks: For employers, these contracts come with long-term financial commitments and more complex legal obligations regarding termination.

2. Fixed-Term Contract

This is your go-to contract for specific, temporary needs with a clear end date.

  • When to Use: To meet temporary staffing needs, such as a seasonal demand, covering a parental leave, or for a specific project with a defined timeline.
  • Duration: Has a specific start and end date. It provides predictability for both parties.
  • Pay and Benefits: Employees on fixed-term contracts often receive similar benefits to permanent employees for the duration of their employment.
  • Drawbacks: For employees, there is job insecurity at the end of the term. For employers, workers may have reduced commitment since they are not a permanent part of the team.

3. Temporary Employment Contract

Often confused with fixed-term contracts, this model is typically used for short-term, urgent needs. These roles are commonly filled through a staffing agency, creating a more complicated employment relationship.

  • When to Use: For flexibility in filling immediate or unpredictable staffing needs, such as covering an employee absence or managing an unexpected increased workload.
  • Duration: Short-term in nature, typically lasting up to a year. Unlike a fixed-term contract, a temporary contract does not usually require advance notice for termination by either party.
  • Pay and Benefits: Temporary employees often receive minimal job security and limited or no benefits compared to fixed-term or permanent employees.
  • Drawbacks: High turnover can be costly for employers in terms of ongoing training and low employee engagement.

4. The Freelancer/Independent Contractor (1099) Agreement

A 1099 employment contract, also known as a freelance or independent contractor agreement, is a legal document that outlines the terms of work between a self-employed individual and the hiring organization.

This model is perfect for engaging contingent workers for specific projects, such as a business hiring a freelance graphic artist to create a design or a tech company hiring a programmer for a short-term project.

  • When to Use: When you need a self-employed expert for a specific, project-based task where you control the result, not the process or methods.
  • Duration: Defined by a Statement of Work (SOW) with clear deliverables and deadlines.
  • Pay and Benefits: Payment is often on a piece rate or a flat fee for the completed project. The contractor is responsible for their own taxes and benefits. A 1099 form is an IRS document that reports payments to them.
  • Drawbacks: For the employer, there is a risk of misclassifying the worker, which can lead to severe penalties. For the freelancer, there is no job security or benefits.

5. Casual Contract

Casual employment contracts are flexible work agreements where workers are hired on an as-needed basis.

  • When to Use: When you need someone new but can't specify a regular work schedule. This is a cost-effective and flexible method for staffing during periods of fluctuating demand, like seasonal holidays.
  • Duration: There is no guarantee of hours or a long-term commitment.
  • Pay and Benefits: Typically, casual workers are not eligible for benefits like paid time off or medical insurance.
  • Drawbacks: Unpredictable income for the worker and the potential for high turnover for the employer.

6. Zero-Hour Contract

Zero-hour contracts are similar to casual contracts but are based on the legal concept of "mutuality of obligation." This means the employer is not obligated to offer a minimum number of working hours, and the employee is not obligated to accept the work offered.

  • When to Use: For flexible work where the employer needs staff to be on-call with no guaranteed hours.
  • Duration: Indefinite, with no guaranteed hours.
  • Pay and Benefits: Zero-hour workers are entitled to some statutory employment rights, such as paid holidays and the national minimum wage, but they typically do not receive other benefits.
  • Drawbacks: An unstable income for the worker and the risk of low employee engagement.

7. At-Will Contract

As noted above, many permanent contracts in the U.S. are at-will. This is the standard employment arrangement in most states.

  • When to Use: When you want flexibility in terminating employees.
  • Duration: Indefinite, but either the employer or employee can end the employment relationship at any time, for any legal reason, without prior notice.
  • Pay and Benefits: While pay and benefits are defined, there is no job security.
  • Drawbacks: The lack of job security for workers can lead to a less stable workforce for employers.

8. Internship Contract

An internship contract is an agreement between an intern, usually a student or recent graduate, and an employer, allowing the intern to gain practical skills, training, and industry experience.

  • When to Use: To assess potential hires in a cost-effective way while providing a valuable learning experience for students.
  • Duration: Short-term, often for a predetermined duration.
  • Pay and Benefits: Internships can be paid or unpaid. Unpaid internships are legal only if the internship meets the "primary beneficiary test," meaning the intern is the main one who benefits from the agreement. In most cases, internships do not offer benefits.
  • Drawbacks: Limited or no financial compensation for interns and the potential for exploitation if the internship lacks proper regulation.

9. Remote Work Agreement

A remote work agreement is a formal document, usually attached to an existing employment contract, that allows employees to work outside the traditional office.

  • When to Use: When you want to offer flexibility, increase productivity, and access a wider talent pool.
  • Duration: Varies.
  • Pay and Benefits: The agreement specifies job duties, compensation, company expense policies, and equipment requirements.
  • Drawbacks: Potential data security risks, communication challenges, and issues with team cohesion.

10. Union Contract

A union contract is a legal agreement between a union and an employer that outlines wages, work hours, job duties, benefits, vacation time, and job security.

  • When to Use: In industries like construction, healthcare, and public services where a unionized workforce exists.
  • Duration: The terms are set for a specific period (e.g., 3-5 years).
  • Pay and Benefits: Designed to protect workers' rights, these contracts ensure fair treatment and include grievance procedures.
  • Drawbacks: Requires strict adherence to a collective bargaining agreement, which can be complex and may limit managerial flexibility.

How to Choose the Right Employment Contract

In some situations, it’s obvious which contract you should use. But sometimes the choice isn’t always clear. Here are three steps to help you determine the best option for your situation:

1. Assess the Role’s Duration

The length of employment is crucial. For short-term requirements, a fixed-term contract is usually the best choice. For ongoing roles, a permanent contract offers stability for both the employee and employer.

2. Evaluate the Level of Supervision Needed

Assess the amount of oversight required for the role. If it requires minimal supervision, a freelance or independent contractor agreement may be the best choice. For positions requiring more oversight, a traditional full- or part-time contract may be better.

3. Understand Employment Laws

Understanding the federal, state, and local employment laws that apply in your situation is critical. A firm grasp of these laws will help you pick the proper contract and avoid potential legal issues, such as worker misclassification.

Key Employment Contract Clauses to Know

An effective contract goes beyond just defining the basic working relationship. It includes clauses that protect both parties and set clear expectations.

  • Job Responsibilities: To outline a worker's responsibilities, provide a clear and concise description of the role. Begin with a brief overview of the position, then list the main duties and tasks expected. Be sure to state that the list is not all-inclusive and that other duties may be assigned as the role evolves.
  • Termination Clauses: These clauses outline the conditions and procedures for ending the employment relationship. They cover grounds for termination, notice periods, and severance pay. A well-written termination clause clarifies and limits liability for both the employer and employee.
  • Non-Compete and Confidentiality Clauses: These clauses should be tailored based on the employee's role and level. For example, executive contracts may include broader non-compete and confidentiality provisions, while independent contractor agreements may use non-competes cautiously. Across all contract types, it's important to verify that restrictions are reasonable, legally compliant, and protect legitimate business interests.

A comprehensive employment contract simplifies dispute resolution and saves time and resources for all parties. By using a data-driven approach, you can streamline the hiring process and ensure every team is closely aligned.
