Workforce Glossary Term

Rotational Worker

A field worker employed on a fixed schedule of alternating work and rest periods, such as 14 days on and 14 days off. Subcontractors must account for rotation cycles when planning crew mobilisation and maintaining consistent headcount on site.

Related Terms

Stand Down

Workforce

A directive to halt all work on-site, typically issued by the prime contractor or operator. For subcontractors, a stand down means crews stop billable activities immediately. Depending on contract terms, standby rates may or may not apply during this period.

Onboarding

Workforce

The process a subcontractor completes before starting work for a new client or general contractor. It typically includes submitting insurance, certifications, and banking details for payment setup. Delays in onboarding can push back mobilisation and hold up first invoices.

Field-to-Office Ratio

Workforce

The number of field workers supported by each administrative/office employee. A ratio of 10:1 is common for paper-based operations; digitized operations often achieve 30:1 to 40:1.

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.

Wrench Time

Workforce

The percentage of a technician's shift spent on hands-on productive work versus travel, waiting, or admin tasks. For subcontractors, low wrench time means billing inefficiencies and reduced daily output. Clients often track it to evaluate crew productivity on site.

SPARK (Spreading Prosperity and Advancing Resilience With Knowledge)

Workforce

A federal initiative aimed at strengthening economic opportunity and business resilience for trades and service contractors. It supports workforce training, skills development, and financial stability programmes. Subcontractors may access funding or resources through SPARK to grow capacity and weather market downturns.
