Even if it were better for the employee to be married to their job (which is doubtful - see: the many articles telling us that the best way to get a raise is to negotiate your new starting salary), I worry that this post could be taken to mean that you should be loyal to your company in the current real world. Your employer does not want to marry you, and will in fact drop you as soon as something better comes along. If you're the only one acting as if it's a long-term thing, you're the sucker.
