A temporary worker brought in to cover a single shift vacancy without joining the regular crew rotation. Common in oil sands and remote site operations when a crewmember is absent unexpectedly. Subcontractors often use slip fills to maintain headcount without committing to long-term hires.
Slip Fill
Related Terms
BLS (Bureau of Labor Statistics)
WorkforceA U.S. federal agency that tracks wage rates, employment trends, and labour costs by trade and region. Subcontractors use BLS data to benchmark crew rates and support bid pricing. It also publishes injury and fatality statistics relevant to oil and gas and construction fields.
Fissured Workplace
WorkforceA jobsite where work is performed by multiple layers of subcontractors rather than direct employees of the site owner. For field service companies, this means accountability, liability, and payment flow through several parties. Subcontractors must track their position in the contracting chain carefully.
Planning and Scheduling
WorkforceThe process of organising crew, equipment, and tasks to meet project timelines and client requirements. Effective scheduling helps subcontractors avoid costly downtime and mobilisation conflicts. It directly impacts labour utilisation, job sequencing, and resource availability across multiple sites.
Utilisation
WorkforceThe percentage of time your crew or equipment is actively deployed on billable work. Low utilisation means idle resources eating into your margins. Subcontractors track this closely to assess profitability and plan workforce levels.
CES (Current Employment Statistics)
WorkforceA monthly U.S. Bureau of Labour Statistics survey tracking employment, hours, and earnings across industries. Field service subcontractors use CES data to benchmark wage rates and spot labour market trends. It helps inform bid pricing and crew cost projections in competitive markets.
Registered Apprenticeship
WorkforceA provincially recognised training program combining paid on-the-job hours with technical schooling to certify tradespeople. Subcontractors hiring apprentices must meet regulated journeyperson-to-apprentice ratios on site. Completing the program earns workers a Red Seal or provincial trade certificate recognised across Canada.
