Educative process relies on the active interrelation of teacher, student, and learning environment. But it is the teacher who has the control over the two elements and professionally exposed to different challenges including workload intensification. Such educational problem has become one of the major foci of educational researchers since the last half of the 20th century due to the evolution of teaching-learning and education in general. This paper was approached using Apple's original thesis of workload intensification and the three refinements formulated by Ballet & Kelchtermans, namely: there are multiple sources of intensification, the intensification impact is mediated, and the intensification impact is differentiated. The study aims to better understand the nature of intensification and its underlying impact on the teaching quality of a teacher in qualitative terms.
