The values of human labor and teacher's work have been reflected on the basis of lexicographical sources and research reflections of famous Ukrainian and Polish pedagogues, such as T. Novatskiy, N. Nychkalo, Pope Paul II, G. Skovoroda, Z. Vyatrovskiy, I. Zyazyun. Among the existing values presented in lexicographical sources the following characteristic of the concept is chosen: "Work is the inspiration, the inner beauty of the human, spiritual richness, and self-development of a person." On the basis of literary analysis of philosophical and pedagogical works of G. Skovoroda it has been concluded that the working process was regarded by the great philosopher and educator as pleasure and happiness, in spite of the results. One can achieve this happiness following the command of inner nature due to the relationship with a certain kind of free vocational work. Pope Paul II proves that the priority function of teacher's work is educating people in love, aspiraton of Truth, Beauty, Good, Hope and Freedom, "the awakening of a human in a man." T. Novatsk?y and Z. Vyatrovskiy considered teachers' work through the values of Love, Truth, Beauty, Goodness, Hope, Liberty, Justice, Solidarity. Scientists consider that teacher's work is "free," happy, optimistic and finds its true purpose only when it serves as a source of creative inspiration. The summaryzing of the publications and presentations made by N. Nychkalo proves that the teachers' work is the means of intellectual and creative potential, experience and a sense of human moral dignity.
