One party providing labor to the other party and the other party paying remuneration in return. In this relationship, labor refers to all kinds of human activities, regardless of whether they are physical or mental. On the other hand, the remuneration paid as consideration is interpreted as not limited to money only, but including anything that has economic value, without regard to its type.
Additionally, the term 'employment' is sometimes interpreted to include self-employment and family labor in the meaning of taking up a job. For example, in contexts such as employment structure or employment issues, 'employment' is used in a broad sense. However, the English term 'employment' originates from the meaning of 'to employ,' and in today's context where employer-employee relationships have evolved into wage labor, employment generally refers to hiring relationships excluding self-employment and family labor.
