Stop candidate ghosting before the first shift.
Underheard calls and texts candidates who went quiet, asks what changed and gets the answer to your recruiter before the shift needs cover.
Still on for Cedarvale tomorrow?
I wasn’t sure who supplies the boots.
I’ll connect you with Maya.
Keep candidate answers in the systems you use




What should you send now?
Send one message that names your agency, repeats the assignment and makes a reply easy. Give the candidate a specific deadline, with enough time left to arrange cover.
“Hi Nolan, this is Meridian Crew. Are you still available for tomorrow’s 2 p.m. packing shift at Cedarvale Packaging? Reply yes, no, or tell me what changed. Please reply by 10 a.m. tomorrow.”
For another assignment, use: “Are you still available for [shift] at [site]? Reply yes, no, or tell me what changed.” Add your agency name and reply deadline before sending.
If the answer reveals a problem, resolve it before counting the worker as confirmed. Underheard follows up by phone, checks availability and connects your recruiter when the worker needs help.
Give silence a simple reply.
Underheard texts before calling, keeps the conversation together and gives your recruiter the reason behind a changed answer. US texting is live.
Make the answer easy.
Offer yes, no or a chance to explain what changed.
Bring in your recruiter.
Underheard shares a short spoken summary before handing over the live call.
“Nolan wants the packing shift. He needs to check the boots. Can you help?”
Leave a useful voicemail.
Underheard leaves the message and calls back on the schedule you choose.

What counts as candidate ghosting?
Candidate ghosting means someone stops replying without telling you they have withdrawn. Record the stage where contact stopped. An unanswered outreach call, a missed interview and a missed first shift need different next steps.
A worker who says no has given you a decision. Someone who has read a message but has not answered still needs a follow-up. Check with the site before recording an absence, and keep the reason unknown until you hear it.
Why do candidates ghost recruiters?
A competing offer, a long wait or unclear job details can leave a candidate silent. For temp assignments, ask about the practical details before deciding they lost interest. Your next question should help them explain the change.
- Another offerAsk whether the candidate accepted other work and when they are next available.
- Slow updatesTell them who will respond next and when, so they know the assignment is still moving.
- Pay or hoursRepeat the hourly pay, shift length and start time. Check whether those terms still work.
- Getting to workCheck the location, transport and required equipment before you ask for a final yes.
Underheard asks about availability and follows the answer. A worker can explain a concern in 120+ languages, and Underheard switches language mid-call.
Know what each reply means.
Underheard calls your candidate list and records what each person says. You see who accepted other work, who needs help and who still needs another attempt.
- Calls at any hour on your chosen schedule
- Availability checked by calls and texts
- Your recruiter confirms bookings before they go out

Follow up in this order.
- 1Text the assignment.Name your agency, shift and site. Ask for yes, no or what changed. Include a reply deadline the worker can act on.
- 2Call the silent candidates.Underheard asks if the work still fits. Check pay, hours, transport and equipment, then connect your recruiter for anything that needs a person.
- 3Leave voicemail and retry.Underheard leaves a voicemail and calls back when you choose. Keep attempts in one worker thread so your recruiters see the previous contact.
- 4Confirm the whole shift.Get an explicit yes after checking the start time, entrance and site contact. Send the agreed details in writing and record any remaining question.
- 5Arrange cover at cutoff.If the worker remains silent, tell your client and contact available replacements. Your recruiter confirms the replacement booking and records the original outcome.
Choose the cutoff from your cover needs. In this sample, a 10 a.m. deadline leaves four hours before the 2 p.m. shift. Use your agency’s actual travel and booking times.

How do you confirm first shifts?
Ask for a clear yes after reviewing the details that decide whether someone can attend. An accepted offer from last week still needs a current availability check before the assignment starts.
- The workConfirm pay, role, shift hours and the date. Ask whether anything has changed since acceptance.
- The arrivalGive the entrance and site contact. Ask how the worker will travel and whether that plan is settled.
- The equipmentList required clothing and personal protective equipment. Resolve who supplies each item before confirming readiness.
In the Cedarvale example, Nolan’s reply opens a question about boots. Maya checks the requirement and speaks with him before confirming the shift. Underheard keeps that call and its answer with his earlier messages.
Keep checking after the first day. Underheard handles first-week check-ins and on-assignment messages, so your agency can hear about a problem before the next shift.
Put the reason beside availability.
Underheard sends answers into Bullhorn, Avionté, TempWorks and your other connected systems. Your recruiter opens the worker record and sees what changed, what is settled and what needs a call.
- Availability and your custom fields filled from answers
- The transcript and recording on the worker’s page
- Calls, texts, WhatsApp messages and emails in one thread

When should you stop chasing?
Stop waiting when further delay leaves too little time to cover the shift. Set that point before outreach starts, and tell candidates when you need their answer. There is no single waiting period that fits every assignment.
At the cutoff, notify your client and contact workers available for the opening. Record the attempts and leave the reason as unknown if nobody answered. If the original candidate replies later, check whether the place is still open before offering it again.
Use the answer to plan the next contact. Someone who accepted other work can give you a future availability date. For shift preparation, see how to stop no-shows.
What does candidate ghosting cost?
Start with the shift hours your agency actually lost. Multiply unfilled billable hours by your contribution margin per hour. Add extra recruiter hours multiplied by the loaded hourly cost of that time.
- Lost shift marginUnfilled billable hours × contribution margin per hour. Use margin after direct worker costs.
- Extra recruiter timeAdditional hours spent chasing or arranging cover × loaded recruiter cost per hour.
- Replacement coverExclude hours a replacement worked from lost hours. Count any extra cover cost once.
Use your own payroll, billing and contact records. Track added overtime or client credits separately, then check that the same loss has not entered two parts of your total.
How do you measure improvement?
Track replies, confirmed assignments and actual arrivals as separate counts. A yes to hearing about work differs from a yes to a specific shift. Check arrival with the site before marking attendance.
- At your cutoffCount contacted candidates, replies, explicit confirmations and unresolved questions for the assignment.
- After the shiftRecord arrivals, replacement cover and unfilled billable hours against the same job order.
- Across similar shiftsCompare the same clients, lead times and shift types. Include recruiter time spent on follow-up.
Keep these definitions steady as you change your follow-up. You can then see whether faster answers gave your team more time to resolve problems and fill the openings.
