Reference excerpt

A fake job, ghost job, or phantom job is a job posting for a non-existent or already filled position. The employer may post fake job opening listings for many reasons:

Inflating statistics about their industries Protecting the company from discrimination lawsuits Fulfilling requirements by human-resources departments Identifying potentially promising recruits for future hiring Pacifying existing employees with the premise that the company is looking for extra help Retaining desirable employees Information-gathering on competitor wages There is a rising trend in employers promising remote work as "bait," and it underscores the relative power of the employers in the job market. According to the career coaching service SamNova, a fake job listing can often be spotted as one that is either continuously open or repeatedly posted. These listings may have catchy titles, vague descriptions, a lack of detail, or contain reposts of previous listings. A survey conducted by Clarify Capital has concluded that many companies and government entities have tricked job seekers with fake ads without the intent of hiring. A 2025 study by recruiting platform Greenhouse Software showed at least one in five job postings in the US is fake or never filled.

Legality Ghost Jobs are generally legal worldwide, though they may violate information privacy laws or consumer protection law in specific contexts in some countries.

Canada In January 2026 a law in the province of Ontario in Canada intended to curb the practice went into effect. Under the law, companies with at least 25 employees must disclose whether a vacancy is actively being filled in a job listing, inform job applicants about the status of their job candidacy within 45 days of a job interview and whether a decision to hire an employee has or has not been made.

United States In 2026, a number of US states considered legislation against ghost jobs. New York state passed a bill proposing requiring employers to disclose when they expect an advertised role to be filled and levying fines for violating these rules. This bill was approved by both houses of the state legislature. As of August 2026, it was awaiting Governor Kathy Hochul's review. New Jersey had a pending bill requiring employers to state whether the position is open and provide a hiring timeline, while allowing some leeway for keeping unavailable position listings open under some circumstances, with clear labeling. The state of Pennsylvania had a bill introduced by Representative Jim Prokopiak require employers to list accurate hiring intentions and establish timelines to remove posts after positions are filled.

Worked examples

Example 1 — a first encounter with Ghost job

Start with the simplest possible case. Write down what Ghost job claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Ghost job before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Ghost job ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Ghost job

In research: Ghost job appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Ghost job in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Ghost job is common in secondary-school and first-year university syllabi. It links to neighbouring topics Business term stubs, Confidence tricks, Deception, so understanding it makes those chapters shorter.
In everyday life: Look for Ghost job outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
