An inside job is a crime, usually larceny, robbery, or embezzlement, committed by a person or persons in a position of trust who is authorized to access a location or procedure with little or no supervision, e.g., a key employee or manager. The perpetrator can also be a former employee who still has specialized knowledge necessary to facilitate the crime.

Pulling off TheCaper can be quite difficult even for an expert criminal. Guards can have unpredictable schedules. There are likely to be alarms and other security systems with which they are unfamiliar, or even completely unaware of. And there's always the possibility that they stage a successful break-in, only to discover the MacGuffin has been moved elsewhere.

All of the above wrinkles are made at least a little smoother when the perpetrator has an insider's knowledge of the target, or even the authority to make changes (to guard schedules, security systems, etc.) to make the target more vulnerable. This perpetrator may be a lone operator pulling off a plan of their own design, the mastermind of a team of crooks, or an "[[TheMole inside man]]" in the employ of a third-party accomplice or accomplices. If the latter, they may be a willing participant or the victim of blackmail, MindControl, or some other means of coercion.

TruthInTelevision: in RealLife, embezzlement and other theft by employees is one of the top causes of loss in businesses such as retail, outpacing external theft by a wide margin.

Can overlap with TheMole when the inside man is part of an external criminal organization. Inside jobs are a common method of pulling off TheCaper, with the inside man consequently being a member of the CaperCrew. If the crime in question is a BankRobbery, the inside man will almost invariably be a BankTeller.

Generally unrelated to OutsideManInsideMan, unless the "inside man" ultimately undergoes the same HeelFaceTurn as the outside man. For the film of the same name, see ''Film/InsideMan''.

'''Note: as a trope dealing with betrayal, expect spoilers to be unmarked!'''



* ''Film/{{Scorched}}'' details three different plots to rob a bank, all of which were initiated by bank tellers.
* The mastermind behind the mall robbery in ''Film/PaulBlartMallCop'' turns out to be one of Blart's trainees.
* Averted, despite the title, in ''Film/InsideMan''. The ending reveals none of the robbers were bank employees.
* In ''Film/OfficeSpace'', the protagonist recruits two of his coworkers in a scheme to rob Initech, their employer.
* As in the novel, the plot of the film ''Film/JurassicPark'' is kicked off by park employee Dennis Nedry sabotaging the park's security systems in order to facilitate his theft of dinosaur embryos to sell to Biosyn, one of Ingen's competitors.
* Subverted and then played straight in ''Film/TheTown''. The robbery at Claire's bank did not involve an employee accomplice but the cops think that there might have been one. When Claire quits her job, it raises red flags and when her relationship with Doug is discovered, she is accused of being that accomplice even though the audience knows she is innocent. The later robbery at Fenway Park involves an inside man, a Fenway employee who owes Fergie a lot of money and hopes to wipe out his debt by providing the robbers with access to the money room.
* In ''Film/{{Armored}}'' six security guard working for an armored truck company decide to steal the money they are guarding and make it look like they were robbed while transporting the money to its destination. They figure that if all of them are part of the theft then no one needs to get hurt. However, things do not go according to plan, a witness is killed and one of the guards decides to stop the others any way he can.
* In ''Film/{{Cliffhanger}}'' the bad guys rob a US government plane transporting $100 million in uncirculated $1,000 bills while it is flying over the Rockies. This daring and extremely dangerous heist is only possible because one of the federal agents guarding the money is actually working for the bad guys and kills the other guards.
* The film ''Flawless'' (starring Michael Caine and Demi Moore) follows the plan of a diamond exchange house's elderly janitor (Caine), who after his many years attending to the place knows its every security flaw.
* In ''Film/TheScore'' Jack plans to steal a priceless scepter from the Montreal Customs House. He gets a job as a janitor in the Customs House so he has access to the building and can see the security measures first hand. He even goes as far as to pretend to be mentally disabled so he appears harmless and beneath suspicion.

* In ''Literature/{{Thunderball}}'', SPECTRE co-opts a NATO officer to steal a pair of nuclear weapons. This was subverted in [[FilmOfTheBook the film version]] of ''Film/{{Thunderball}}'', where SPECTRE replaces the officer with a double, but played straight again in the remake, ''Film/NeverSayNeverAgain'', where the officer reprogams two nuclear missiles so the warheads can be recovered by SPECTRE.
* In both the novel and film ''Literature/JurassicPark'', the plot is kicked off by park employee Dennis Nedry sabotaging the park's security systems in order to facilitate his theft of dinosaur embryos to sell to Biosyn, one of Ingen's competitors.
* Referenced but {{averted}} in ''Film/{{Jumper}}''. Davy cleans out a bank vault with his teleportation power. Later, somebody theorizes in his hearing that the robbery must've been an inside job since there wasn't any sign of forced entry.
* In "Silver Blaze", two of Literature/SherlockHolmes' hints are "the curious incident of the dog in the night-time" ([[AbsenceOfEvidence it was completely silent]]) and the fact that powdered opium was put in a dish spicy enough to hide its taste. Both point at an inside job, because a dog would not have kept silent had it sensed an intruder, nor could an outsider have arranged for a spicy dish to be served on that particular night.

* An episode of ''Series/{{CSI}}'' has the team investigating an officer-involved shooting during the robbery of a grocery store. When the surveillance tapes reveal that there was much more money in the registers than store policy recommended, suspicion quickly falls on the cashier on duty, who soon admits to being in league with the robbers.

* ''Series/BreakingBad'':
** Walter steals hard-to-get equipment and chemicals from his high school to kick-start his meth-cooking operation. The fact that there's no sign of forced entry immediately tips off DEA agent Hank that it was an inside job.
** For a short time, Jesse skims some of the excess product he and Walt produce for Gus Fring to sell on his own.
** It comes out that Gus Fring's operation is supplied with methylamine by Lydia, who facilitates its theft from her employer, Madrigal.
** Later, Lydia uses her inside knowledge of Madrigal's freight shipments to tip Walt's crew off that a train hauling a tanker car full of methylamine will be vulnerable while passing through a "dead zone" with no cell coverage.
* In one episode of ''Series/ItTakesAThief2005'', Jon is charged with robbing a mechanic's business (as opposed to houses like the show normally covers). Rather than risk setting off the alarm and having to pick a lock, [[DungeonBypass Jon just bribes an employee to not set the alarm and unlock the back door]]. Naturally, with all the security features disabled, Jon effortlessly cleans the place out.
* One episode of ''{{Series/Monk}}'' features this trope [[spoiler: taken to its logical extreme]]. Monk's bank is robbed and he goes undercover as a guard to crack the case. He soon discovers that the bank manager was in on the robbery and murdered as a result. But later, he discovers [[spoiler: the ''entire bank staff'' committed the robbery.]]
* In an episode of ''Series/{{Bones}}'' the VictimOfTheWeek had been trying to talk his girlfriend, who works at a currency exchange, to leave the back door unlocked so he and an accomplice could rob the place when nobody was there, but she refused.
* On ''Series/PersonOfInterest'' Reese and Finch are trying to save a Number who is a security guard working for an armored truck company. They find out that he is about to guard a very valuable platinum shipment and they suspect that the shipment will be attacked by robbers who are likely to kill the guards. What they fail to consider is that the robbery is actually an inside job and the Number is the mastermind behind it.

* In ''Webcomic/{{Gaia}}'', as part of the plan to break the capitally WronglyAccused Lilith out of prison, one of the protagonist gets hired in the jail.

[[folder: Real Life]]
