Offer Letters for Contract-to-Hire Positions: What to Include

What Is a Contract-to-Hire Arrangement?

A contract-to-hire (also called temp-to-perm or contract-to-permanent) is an employment arrangement where a worker starts as a temporary or contract employee for a defined period, with the possibility of converting to a permanent full-time role based on performance and business needs.

This approach benefits both parties: the employer gets to evaluate the worker's skills, cultural fit, and work quality before making a permanent commitment, while the worker gets a foot in the door and an opportunity to prove themselves.

However, contract-to-hire arrangements are more complex than standard employment, and the offer letter needs to address several unique considerations.

Structuring the Contract Phase

Employment Classification

Clarify the worker's classification during the contract phase. There are two common structures:

Direct contract employee — The worker is employed directly by your company as a temporary employee. You handle payroll, taxes, and applicable benefits.

Staffing agency employee — The worker is employed by a staffing agency and assigned to your company. The agency handles payroll and taxes. You pay the agency a rate that covers the worker's compensation plus the agency's margin.

The offer letter structure differs depending on which model you use. For direct hires, you issue the offer letter. For staffing agency arrangements, the agency typically handles the initial offer, and you issue a separate offer letter if and when conversion occurs.

Contract Duration

Specify the expected length of the contract phase:

"The initial contract period will be approximately 90 days, beginning on [start date] and ending on approximately [end date]. The contract period may be extended or shortened at the company's discretion."

Common contract periods are 90 days, six months, or one year. The length should be sufficient to evaluate the worker's performance but not so long that it delays a decision unnecessarily.

Compensation During the Contract Phase

State the contract-phase compensation clearly:

• Hourly rate or salary equivalent
• Pay frequency
• Whether overtime is applicable (it usually is for hourly contract workers)
• Whether the contract rate differs from the anticipated permanent rate

Example: "During the contract period, your compensation will be $45.00 per hour, paid biweekly. You will be classified as a non-exempt employee and eligible for overtime pay."

Benefits During the Contract Phase

Specify which benefits, if any, are available during the contract period:

If benefits are available: "During the contract period, you will be eligible for the company's health insurance plan and paid time off on the same basis as other full-time employees."

If benefits are not available: "Benefits, including health insurance and paid time off, are not available during the contract period. Upon conversion to permanent employment, you will become eligible for the company's full benefits package."

If through a staffing agency: "During the contract period, benefits are provided through [Staffing Agency], not through [Company Name]. Please contact [Agency] for details on available benefits."

Addressing the Conversion to Permanent Employment

Conversion Language

The most critical part of a contract-to-hire offer letter is how you describe the potential conversion. The language must be clear that conversion is a possibility, not a guarantee:

"At the end of the contract period, the company may, at its sole discretion, offer you a permanent full-time position. Conversion to permanent employment is not guaranteed and will be based on your performance, business needs, and other factors."

Conversion Evaluation Criteria

While you do not need to provide a detailed rubric, it is helpful to indicate what factors will influence the conversion decision:

"The conversion decision will be based on your performance, demonstrated skills, team fit, and the company's ongoing business needs. Your manager will provide regular feedback throughout the contract period."

Permanent Role Terms

If you know what the permanent role terms will look like, include a summary:

"If a permanent offer is extended, we anticipate the following terms: annual salary of $95,000, standard benefits package including health insurance, 401(k) with employer match, and 20 days of PTO. Permanent offer terms are subject to change and will be confirmed in a separate offer letter."

If the permanent terms are not yet defined, note that they will be determined at the time of conversion.

At-Will Employment During the Contract Phase

Even though the contract phase has a defined end date, the employment relationship should remain at-will:

"Your employment during the contract period is at-will. Either you or the company may terminate the employment relationship at any time, with or without cause, regardless of the anticipated contract end date."

This ensures the company is not obligated to keep the worker for the full contract duration if performance issues arise.

Handling Common Contract-to-Hire Scenarios

Early Conversion

If the worker exceeds expectations, you may want to convert them before the contract period ends. The offer letter can address this:

"The company reserves the right to offer permanent employment at any time during the contract period."

Contract Extension Without Conversion

Sometimes you need more time to evaluate or the permanent headcount is not yet approved. The offer letter can provide for extensions:

"The contract period may be extended by mutual agreement. Any extension will be documented in writing."

Decision Not to Convert

If you decide not to convert the worker, the contract simply ends. With at-will language in place, you can also end it before the contract period expires.

Conversion With Different Terms

Sometimes the permanent role differs from the contract role — different title, different team, different compensation. If this is a possibility, note it:

"The terms of any permanent offer may differ from the terms of the contract engagement."

Legal Considerations

Benefits Eligibility

Under the ACA, workers who average 30 or more hours per week over a measurement period may be considered full-time employees eligible for health insurance, regardless of their "contract" label. Make sure your benefits administration is ACA-compliant.

Co-Employment Risk (Staffing Agency Model)

If the worker is employed by a staffing agency, be careful about exercising too much control over their day-to-day work, which can create a co-employment situation. Co-employment means both the agency and your company are considered employers, creating shared liability for employment law compliance.

Unemployment Insurance

Contract workers who are not converted may be eligible for unemployment insurance. Factor this into your cost calculations.

Tenure and Seniority

Clarify whether time spent as a contract worker counts toward tenure, seniority, or benefits eligibility upon conversion:

"If you are converted to permanent employment, your original contract start date will be used for purposes of determining tenure and benefits eligibility."

Common Mistakes in Contract-to-Hire Offer Letters

• Guaranteeing conversion — Language suggesting conversion is automatic creates binding expectations
• Not specifying contract duration — Open-ended contracts create uncertainty for both parties
• Ignoring benefits eligibility — ACA requirements may apply regardless of the "contract" label
• Failing to issue a conversion offer letter — The transition from contract to permanent should be documented with a new offer letter
• Unclear compensation transition — The candidate should understand how pay changes upon conversion
