Daily oil & gas and construction news for subcontractors

WorkforceGlossary Term

Shoulder Season

The transitional period between peak and slow seasons when project volumes drop and scheduling becomes unpredictable. Subcontractors often face reduced call-outs, crew utilisation gaps, and tighter margins during these windows. Common in oilsands and construction work between summer and winter campaigns.

Energy Workforce & Technology Council (ewtc)

Workforce

A U.S.-based industry association representing energy sector employers and workforce development initiatives. For subcontractors, it publishes training standards and competency frameworks used by operators to qualify field crews. Membership can signal credibility when bidding on contracts with major energy clients.

Colocation

Workforce

When a subcontractor embeds personnel or equipment at a client's site for an extended engagement. This reduces mobilisation costs and improves response time for ongoing work. It is common on large construction or production sites requiring continuous support.

Scheduling Compression

Workforce

When a client shortens a project timeline without reducing scope, forcing subcontractors to mobilise faster and overlap tasks. This often drives up labour costs through overtime and split shifts. Subcontractors should ensure contracts address compressed schedules with change order provisions.

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.

Slip Fill

Workforce

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.

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.
