就く in sports jargon I know that {means “to be hired”. But does it have a separate meaning in sports jargon (soccer, baseball...) I’m referring to the following sentence:

> know that {}means “to be hired”.

While that is not incorrect, I would rather suggest that you remember the meaning as "to assume a position". Why? Because while is in the active-voice form, "to be hired" is in the passive voice.

The in the sentence:

> {}{}{}{}

is not all that different in that it means:

> "Everyone ran to assume a defensive position."

Sports or business, you are assuming/taking a certain position. That is what means.
