This FAQ covers the most common questions from plant managers, procurement teams, and HR managers evaluating industrial trade staffing agencies for the first time or switching providers.
How do staffing agencies find certified welders and pipefitters?
Specialized trade staffing agencies build pre-vetted candidate rosters through direct recruiting from craft union halls, NCCER training programs, AWS and ASME certification databases, and referral networks from previous placements. The best agencies maintain active databases of certified tradespeople with current credentials, TWIC cards, and known shutdown availability. General staffing agencies that also staff office workers and light industrial labor rarely have the depth of certification-verified craft workers that industrial facilities require.
What is the difference between contract and direct-hire staffing for tradespeople?
Contract staffing places tradespeople on a temporary basis where the staffing agency remains the employer of record, handling payroll, taxes, and workers compensation. Direct-hire (permanent placement) transfers the worker directly to the client as their employee, with the agency collecting a one-time placement fee of 18-25% of first-year salary. Most industrial trade staffing is contract-based, with temp-to-perm conversions common after a trial period. Shutdown and turnaround placements are almost exclusively contract because the work has a defined end date.
Do staffing agencies handle OSHA compliance for placed workers?
Staffing agencies are co-employers under OSHA regulations and share responsibility for worker safety with the host employer. The agency is typically responsible for providing OSHA 10 or OSHA 30 training, general safety orientation, and PPE requirements communication. The host employer is responsible for site-specific safety procedures, equipment operation training, and day-to-day supervision. Agencies should always be able to provide certificates of insurance covering workers compensation and general liability, with your facility named as an additional insured.
What markup do staffing agencies charge for industrial trade placements?
Industrial trade staffing agencies typically charge a markup of 30-45% over the worker pay rate for contract placements. This covers employer payroll taxes (7.65% FICA), workers compensation insurance (which is elevated for trades due to injury risk, often 8-15% for welding and pipefitting classifications), general liability insurance, and the agency gross margin. Shutdown and turnaround placements often carry higher markups of 40-50% due to short duration, mobilization costs, and the need to carry workers between shutdowns. See the staffing agency vs in-house recruiting comparison for a full cost breakdown.
How quickly can a staffing agency mobilize certified tradespeople for a shutdown?
Agencies with active, pre-vetted rosters of certified tradespeople can typically mobilize in 24-72 hours for most trades. Specialized roles like NBIC-certified boilermakers or ASME Section IX pipe welders may take longer if the agency does not maintain a dedicated roster for that certification. The best shutdown staffing agencies begin pre-screening workers for upcoming turnarounds 60-90 days in advance of the scheduled start date. See the shutdown turnaround staffing checklist for a detailed mobilization framework.
What is the difference between a pipefitter and a plumber?
A plumber primarily installs and repairs sanitary drain, waste, and vent piping and potable water systems in residential and commercial buildings. A pipefitter works on industrial process piping systems carrying high-pressure steam, chemicals, and petroleum products in refineries, power plants, and chemical facilities. The ASME B31.3 and B31.1 certifications required for industrial pipefitting are fundamentally different from and more demanding than plumbing licenses. A licensed plumber cannot be placed on ASME-qualified process piping work at a refinery. See what is a pipefitter for the full trade overview.
How do staffing agencies verify that a welder certification is current?
AWS certifications can be verified directly through the AWS certification verification system at aws.org using the welder ID number on the certification card. ASME Section IX certifications are maintained by the employer who conducted the procedure qualification test. The WPS (Welding Procedure Specification) and PQR (Procedure Qualification Record) documentation must be provided. Any agency that cannot clearly explain their certification verification process should not be trusted for pressure-containing weld placements.
How do prevailing wage laws affect trade staffing in the industrial sector?
Prevailing wage laws, including the federal Davis-Bacon Act and state equivalents, require that workers on public construction and infrastructure projects be paid the locally determined prevailing wage for their trade classification. For staffing agencies placing tradespeople on public works projects, pay rates must meet the prevailing wage floor, and certified payroll reporting is required. The markup structure is affected because prevailing wages are often higher than open-market rates. See the prevailing wage trade staffing guide for the complete framework.
