Workforce Glossary Term

Spare Capacity

The portion of a subcontractor's available workforce, equipment, or service hours that is not currently committed to active contracts, representing untapped revenue potential that can be offered to clients on short notice or used to absorb surge demand without turning down work.

Related Terms

Geofencing

Workforce

A virtual boundary set around a job site that triggers automatic alerts when workers or equipment enter or leave. Subcontractors use it to verify on-site attendance, automate timekeeping, and support accurate billing. It also helps clients confirm crew deployment without manual check-ins.

CLRC (Construction Labor Research Council)

Workforce

A U.S. research organisation that tracks and publishes construction labour wage rates and collective bargaining data. Subcontractors use CLRC reports to benchmark labour costs and support bid pricing on union projects.

Crew Utilization

Workforce

The percentage of available crew hours that are billable or actively deployed on a job. Low utilisation means workers are on standby or idle, cutting into margins. Subcontractors track this metric to assess workforce efficiency and bid future projects accurately.

Back Wages

Workforce

Unpaid earnings owed to workers for hours already worked. For subcontractors, this often arises from payroll errors, misclassification, or disputed overtime on remote job sites. Unresolved back wage claims can trigger labour audits and project holdbacks.

SJT (Situational Judgment Test)

Workforce

A pre-hire assessment used to evaluate how candidates respond to realistic workplace scenarios. Operators and prime contractors use SJTs to screen field workers for safety judgement and decision-making. Subcontractors may encounter these tests when onboarding crews for client-managed worksites.

Nonemployer Establishment

Workforce

A business that generates revenue but has no paid employees — typically a sole proprietor or owner-operator. Many field subcontractors and independent tradespeople operate this way. Statistics Canada tracks these firms separately in labour and industry data.
