Case study:
There are two companies. Company A is smaller, pays a little less, but is willing to train if you're willing to learn. Company B is larger, pays more, but demands that you have experience up front. Company A is kindof family-like, there's a lot of company picnic type events, a lot of couples work there where one started and encouraged the other to apply. Company B, well, at least one person has gone from Company A to Company B and returned, saying they were "a bunch of cocks."
Recently, however, three employees have gone to Company B, looking for the higher pay and more experience company B offers. Company A wishes them well, but around the office it's kindof taken as fact that these people never planned to stay with A, just used A for the experience and ran, or value the pay over the friendship.
(Someone has also recently applied with company C, which has even higher pay, fewer cocks, requires even more experience, was turned down, but is now on "probation" within company A.)
You, an employee, are kindof intrigued by what Company B offers. You apply, and over the water cooler mention that, oh, B's person in your department likes your stuff, she gave a few suggestions.
"Uh," says another employee, "Why is B's person in your department looking at your stuff? Did you apply there?"
"Well, yeah," you say.
Obviously, this gets to your boss. You are not allowed to take shifts until your application there is denied, at which point you, also, are on "probation," meaning you get the assignments when no-one else in your department can come, because why should we give you the work/training when you've shown a desire to jump ship?
What a fucking dumbass.
