Nevertheless, this childish naive confidence of businessmen, directors and queens of personnel, the slogan "insubstitutable" is not. Theoretically yes. And in practice, the formulation is often smooth or unexpectedly and sharply as diarrhea flows in the "how quickly and adequately set tasks are not indispensable?". No one will guarantee that the new employee will not be worse and there will be no more problems with him. Especially if the employer is mindlessly interested in "resource optimization" and "effective management". In the sense of stupid arrogance, if brief and clear. And such examples are full of: something, a social package, more pay? Go on the road, or go on the road. Further, the flow of diamonds is unlimited: the altruistic, the impasse, the thief, the irresponsible informal, the pofigist, the intricate thief. Plak-plak, can you come back?
