For managers there are few guarantees. Criticism and scrutiny come with the job, as does the inevitability of being sacked at some point.
And while the Hammers have appointed David Moyes as Bilić's successor, the Toffees are still without a permanent manager as David Unsworth continues in the interim.
Italy, too, could soon be without a head coach following Gian Piero Ventura's failure to steer the Azzurri to next summer's World Cup in Russia, creating another attractive opening.
So who are the best out-of-work managers available? Owners, take note, we might be about to save you a few quid.
