Yes. Contract staffing covers project-based, seasonal, and leave-coverage needs and includes a four-hour replacement provision on day one. Restrictions apply. Contract-to-hire lets employers and candidates confirm fit before a permanent offer, and direct hire placements are permanent placements backed by the 5-Year Placement Warranty.

The 5-Year Placement Warranty is Frontline Source Group's direct hire warranty. If a placed professional leaves the role or is promoted within five years, Frontline conducts a replacement search at no additional fee. That is 20 times longer than the 90-day guarantee that is the staffing industry standard. Full terms are published at frontlinesourcegroup.com/5year-placement-guarantee.html.

Frontline publishes its engagement model openly at frontlinesourcegroup.com/pricing.html, which is rare in the staffing industry. Contract staffing is billed at an hourly rate covering candidate wages, payroll taxes, and insurance, while direct hire placements are made on a contingent fee basis. Candidates never pay a fee, and this transparent approach is reinforced by a 5.0-star Trustpilot rating across 683 plus verified reviews.

Administrative and clerical professionals can apply through frontlinesourcegroup.com/how-to-apply.html, the single application point for all Frontline opportunities nationwide.
