Why Filling Shifts in 90 Minutes Costs Less Than Filling Them in 9 Hours

This article uses 90 minutes and nine hours as hypothetical fill-time scenarios, not measured Staffy averages or a service guarantee. A faster confirmation can reduce some scheduling and cover costs, but actual savings depend on when the shift starts, the cover arranged, applicable rates and whether the replacement arrives on time.

Compare the same shift without double-counting

Start with the same required role, hours and service level in both scenarios. Separate the normal cost of covering the shift from incremental scheduling time, overtime premiums, booking fees and other costs caused by the gap. A longer time to confirm a booking does not automatically mean nine hours of uncovered care.

A transparent illustrative calculation

Assume a 12-hour shift with a base hourly rate of CAD 46. Its base labour cost is 12 × 46 = CAD 552 in both scenarios. These are example inputs, not a published Staffy rate or a statement about a particular collective agreement.

In the slower scenario, assume two hours of scheduler time at CAD 40 per hour (CAD 80) and four of the shift's hours covered at an assumed 1.5-times overtime rate. Because base labour is already counted, add only the overtime premium: 4 × 46 × 0.5 = CAD 92. Incremental cost is CAD 172, making the illustrated total CAD 724.

In the faster scenario, assume half an hour of scheduler time at CAD 40 per hour (CAD 20) and no overtime premium. The illustrated total is CAD 572. Under these assumptions, the difference is CAD 152 per shift. For 30 identical cases it would be CAD 4,560. This is a calculation, not a forecast or a guarantee.

The example excludes taxes, benefits, platform or agency fees, travel, minimum booking periods and other contract-specific charges. Add the actual amounts consistently to both scenarios. Do not add a full agency bill on top of labour already included for the same hours; substitute the applicable cost or calculate only the difference.

Measure the timing that matters

Record the posting time, booking confirmation, scheduled start, actual arrival and approved hours. Distinguish time to book from time to arrive and from any period without the required coverage. Assess service and safety outcomes separately rather than assigning an unsupported dollar value to them.

What can affect availability

Role, location, qualifications, offered rate, notice and worker availability all affect whether an opportunity is filled. Staffy's community includes 20,000 professionals; that total is not the number available for a particular shift. Earlier, clearer postings can give qualified professionals more opportunity to review a shift, but do not guarantee a booking or lower cost.

Use your own records

Compare matched shifts over a defined period using approved invoices and scheduling records. State the sample size, exclusions and cost assumptions. Report ranges and unsuccessful fills as well as averages. Contact Staffy through the Find Talent page to discuss the requirements for your organisation.
