Can you please elaborate? I kinda understand in theory, but not in practice. I kinda get the impression that Te-dominant people (ENTJ and ESTJ) have their Fi abused and torn in the corner?
The Personal Growth sections for ESTJs and ENTJs on PersonalityPage give some good insights into it:

In short though (as I understand it), in an under-developed E*TJ their primary Te runs roughshod over all their other cognitive functions - everything gets judged purely on external "objective" criteria. Things are only "good" or "bad", "right" or "wrong" (etc.), based on whether the E*TJ decides they work in the "real world" or not.
This means they have no time for things based on subjective personal values, which can lead them into all sorts of trouble when dealing with the needs and desires of other people.
In under-developed ESTJs their auxiliary Si gets hijacked by Te into only dealing with things that are familiar, that have been done before - which means that the unfamiliar and the new become things to be distrusted or even hated (if the ESTJ is
particularly unhealthy/under-developed). In under-developed ENTJs their auxiliary Ni gets hijacked into thinking that the ENTJs vision/opinion is the
only correct opinion, any others are just plain wrong.
The key for both of them is to fully develop their auxiliary functions beyond the confines and restrictions of their dominant/primary Te. This means that they need to learn to listen to
all the information their Si/Ni gives them, not just the information that supports the judgements their Te has already made.
This helps them to realise that their way/the old familiar way isn't the
only way, or even necessarily a
good way. Because they so value things that actually
work (primary Te) this realisation encourages them to look for a new way to do things, which in turn helps them recognise the value of other people's input, whether that be in the form of new ideas (Ne), physical experiences (Se), or personal values (Fi).
Even fully developed E*TJs will always have a preference for things that can be judged on external "objective" criteria (Te), but they are a lot more comfortable with new ideas/new experiences (Ne/Se), and are also guided in their judgements by a personal value system that places great emphasis on the subjective needs of the individual (Fi).
