The hire who doesn't ask questions in week one is quitting in
A new hire who stops asking questions in week three isn't adapted. They've already started running the math on leaving.
A surprising share of voluntary first-year quits happen between months seven and ten — long after the new hire stopped asking questions.
The standard model: a new hire who asks lots of questions is annoying; a new hire who doesn't is a fast learner. The standard model is wrong. A new hire who asks lots of questions is engaged. A new hire who doesn't is either exceptional, or already deciding the place is not for them.
Most aren't exceptional. Most are conflict-averse, fresh into a job they're not sure about, watching how meetings end and how disagreement is handled. They take notes. They show up. They wait. By month four they have a private list of things they would change if they could; by month seven they decide they can't; by month nine they apply elsewhere.
The miss is that the manager spent week three through twelve being relieved that the new person "is quiet, just gets things done." Quiet hires don't disappear because they're shy. They disappear because they did the math.
The fix is not "ask them how they're doing." That produces "I'm doing great." The fix is to show them how decisions get made. Bring them into a tense one — a hiring decision, a vendor cut, a missed quarter. Let them watch a manager say "I was wrong about that." Let them see who pushes back and what happens to them. The new hire learns more about whether to stay from one half-tense decision than from twelve "how's it going" check-ins.
The hire who isn't asking questions at month three is not adapted. They're auditioning their next job.
