How to reach passive candidates who are not looking

Passive candidate sourcing gets written about as a finding problem. It is not. Finding a senior estimator in Perth who has been at the same firm for six years takes about ten minutes. Getting that person to take your call is the hard part, and it is a writing and timing problem rather than a search problem.

The distinction matters because the two have different fixes. If finding people is your bottleneck, a better search helps. If the people you find never reply, a better search gives you more people who never reply.

Why the standard approach fails

Someone who is not looking has no reason to read your message. They are not checking listings, they have no CV ready, and they were not thinking about their career until you interrupted. Everything follows from that.

A message that opens with your agency's name, mentions an "exciting opportunity" and asks whether they would be "open to a confidential chat" fails because it asks for effort before it offers anything. The reader has to work out what the role is, whether it is a step up, and why you contacted them specifically. Most will not do that work for a stranger.

The variant that fails even harder is the one that flatters. "I came across your impressive profile" tells the reader you sent this to forty people, because a message written for one person does not need to say it was.

What a passive candidate is actually weighing

Nobody leaves a job they are fine with for a job that is merely also fine. The move has to be worth the risk of being the new person again, and the risks are specific: a manager they have not met, a probation period, losing accrued leave and the goodwill of being the one who knows how things work.

So the only messages that get replies name something concrete the current job does not have. In practice it is a short list:

You will not know which applies before you call. But you can guess from the public facts, and a guess stated plainly is far better than a generic approach: "You have been at the same firm six years doing $10m packages. The role I am ringing about is $40m plus and the site is in Osborne Park rather than the CBD."

If that guess is wrong, they will correct you, which is a conversation. Generic messages do not get corrected. They get ignored.

Timing beats message, when you can get it

A message is a guess about whether someone wants to move. Some moments make the answer far more likely, and they are visible from outside.

A firm that has just lost a tender, finished a major project with nothing to follow, been acquired, changed ownership, or had a round of departures in one team is full of people who were not looking last month and are now. The same person who ignored you in March will take the call in September.

This is the part that separates a desk that fills hard roles from one that does not. Not better messages, the same messages sent at the moment somebody has a reason to listen.

The sequence that works

Passive outreach is a sequence, not a message. One attempt is a coin toss regardless of quality.

One: a call, if you have a mobile. A real conversation beats any written message, and most recruiters skip it because it is uncomfortable. Thirty seconds: who you are, the one concrete thing, and a question. If they are busy, ask when suits and ring then.

Two: a short written message within two days, referencing the call. Three or four sentences. The role, the one concrete thing, and what happens next if they are curious. Not a repeat of the pitch in longer form.

Three: something useful, a week or two later. A salary benchmark for their discipline, a note that a competitor has won work, something that is worth reading whether or not they engage. This is where almost everyone gives up and it is where a reasonable number of replies arrive.

Four: a note that closes the loop. "I will stop bothering you. If it changes, here is my number." This one gets more replies than it has any right to, because it removes the pressure.

Four touches over about a month. Most desks stop at two, which is the point where it starts to feel like rejection rather than process.

What to do when they say no

Most will say no, and the no is the most valuable part of passive sourcing if you treat it properly.

Ask one question: what would have to be true for this to be interesting? The answer is the record you have been missing. "Not for less than $180k." "Not unless it is closer to home." "Not until my shares vest in March." Write it down against their name with the date.

That turns a dead approach into a pool entry with a trigger on it. March arrives, you ring, and you are the one person who remembered. That call has a completely different success rate from a cold one, and it cost you a single question you were already in a position to ask.

Where this actually falls over

The failure is rarely the technique. It is that passive outreach competes for time with everything else on a desk, and it loses, because it pays off in weeks while a live brief pays off today.

The practical fix is to accept that and shrink the commitment. Five passive approaches a week, properly written and properly followed up, beats forty in a burst followed by nothing for a month. Five a week is two hundred and fifty a year, which for most desks is more than enough to build a genuine bench in two or three disciplines.

The part that eats the time is not the outreach itself. It is working out who to approach: reading enough of each person's history to know whether they are plausible, and what to say that is specific to them. That reading is the same work whether you do it for five people or fifty.

If you want that part shortened, describing the role in plain words and getting back people already read and checked against each requirement is exactly that job. Rectask Sourcing returns a ranked shortlist with the evidence for each must-have, which is the reading done. What to say to each of them, and when, is still yours, and it should be.

Common questions

What is passive candidate sourcing?

Approaching people who are employed and not applying for roles, rather than working from applications. It matters most in markets where the people who are good at a scarce skill are almost never on the market at the moment you need them.

What is the best message to send a passive candidate?

Short, specific, and naming one concrete thing their current job does not have: money, scope, commute, or getting off a rotation. A guess stated plainly beats a generic approach, because a wrong guess gets corrected and a generic message gets ignored.

How many times should you follow up with a passive candidate?

About four touches across a month, varying the format rather than repeating the pitch. Most replies to passive outreach arrive after the point where the average recruiter has already stopped.

Is passive sourcing better than advertising a role?

They solve different problems. Advertising reaches people who are looking, which is fast and cheap when supply is deep. Passive sourcing is what you do when the people who can actually do the job are all currently employed, which is most senior and most trade-skilled roles.
