Two characters are each doing their thing, whether that's saving the world or just trying not to get fired. For some reason, it turns out that neither can succeed if the other fails. However, the dramatic element is that they can't just cooperate and get both tasks done. It has to be done discreetly, so one or both has to help the other secretly in order to achieve their own goal.

[[folder: Literature ]]

* In the Literature/{{Discworld}}'s Ankh-Morpork, Commander Vimes pursues the law without favor, annoys the rich and power, upsets the finely-balanced alliances of the city's politics and generally makes a nuisance of himself to Lord Vetinari by thumping through his court like a bull in a china shop. This is exactly where Vetinari likes having him around.
* Author LenDeighton's NoNameGiven spy once remarks to someone that he's well known to be a loose cannon who the boss can barely keep under control. He mentions that this is his boss's protection, and the government's protection, as they can disown him if needed. Everyone's happy with this, he gets to do what he has to to get the job done and they can pretend to be [[Film/{{Casablanca}} Shocked, Shocked!]], if he gets in trouble.

[[folder: Live Action TV ]]

* In ''Series/BuffyTheVampireSlayer'' Season 5, this ends up being the case between Buffy and the Watcher's Council. Buffy points out that she needs them to identify Glory but they need her or they're just a bunch of old guys in tweed waiting for her (well, actually, they're waiting for Faith) to die because without a Slayer they have no purpose. So the Council hires back Giles (and after his prompting, gives him all the pay he would have gotten since he got fired to that moment) and in return they tell her who Glory is (a hellgod).
* In ''HogansHeroes'', the heroes frequently have to protect Klink, Schultz, or both from the Gestapo or SS to carry out their schemes.
* On ''TheOffice'', almost everyone else is this for Michael Scott.
* On the FX show ''Terriers'', Hank, an ex-cop, and low-level P.I. Frames The Guilty Party (FramingTheGuiltyParty) in a murder and then tips off his ex-partner Gustafson (who's still a cop and was investigating the crime) about new evidence so he can arrest (and convict) the killer. Gustafson gets great notices for solving the murder, only for something else to unexpectedly go wrong, putting him, Hank, and the whole case in jeopardy. Noty wanting to get himself involved, Gustafson tells Hank he has twenty four hours to fix it (YouHave48Hours). If Hank can't, not only would he be investigated for (and charged with) planting evidence, he'll ruin his friend's career too, for being linked to a frame-up.
