There's a moment every pharmacy manager dreads: it's Tuesday afternoon, you just found out your closer called in sick for Wednesday, and you need coverage fast. You post the shift expecting the worst.

Here's the thing. On ShiftRx, those last-minute shifts actually get filled at a surprisingly high rate.

The Numbers

We looked at shift completion rates across the ShiftRx platform in 2025, broken down by how far in advance each shift was posted.

Shifts posted less than three days before their start time were completed 73.5% of the time. Nearly three out of four. For pharmacists specifically, same-day postings completed at 71%. For pharmacy technicians, 75%.

Even in the one-to-two day window, the numbers held strong: 70% for pharmacists, 78% for techs.

That's a really solid fill rate for shifts that most people would assume are the hardest to staff. The ShiftRx worker pool is responsive, and when a need is clear and immediate, people show up.

Why Short-Notice Shifts Work So Well

A few things are working in your favor when you post close to the start time.

The need is confirmed. There's no ambiguity about whether this shift is actually going to happen. Workers who pick it up can plan around it with confidence.

Workers are looking for immediate opportunities. A meaningful share of the ShiftRx workforce is actively checking the platform for shifts they can pick up in the next day or two. Short-notice postings land right in front of the people who are ready to commit now.

Both sides are motivated. You need coverage, they want hours. That mutual urgency drives follow-through. The data bears this out consistently across both pharmacist and technician roles.

Tips for Getting the Most Out of Every Lead Time

Short-notice shifts perform well on their own, but there are things you can do to improve your fill rates across the board.

Post early when you can, and keep those postings current. Advance posting is great for planning. It gives workers more time to organize their schedules, and it signals that your facility is organized. Just make sure to pull shifts down promptly if your staffing situation changes. Keeping your postings accurate builds trust with the worker pool, and trust translates to better fill rates over time.

When posting on short notice, be specific. Include shift details, any special requirements, and confirm the time is accurate. The easier you make it for a worker to say "yes, I can do that," the faster you'll see a pickup.

Think of your posting history as a reputation. Workers on ShiftRx learn which facilities are reliable. If your postings consistently reflect real, confirmed needs, you'll see stronger engagement from experienced workers who know your pharmacy and can hit the ground running.

The Bottom Line

If you're in a pinch and need someone tomorrow, post the shift. The data says you've got a strong chance of getting it filled. ShiftRx's network is built for exactly this kind of responsiveness.

And if you're the type who likes to plan ahead, keep doing that too. Just treat those early postings as living documents, and update them as your needs become clearer. Both approaches work. The platform is designed to handle the full spectrum.
