The need for satisfying deadlines and reducing costs made construction companies invest in the improvement of productivity throughout the steps of constructing buildings. This study aimed to stratify the workforce‟s productivity in employment categories during the execution of the plaster coating, showing productivity indicators values expressed in man-hours per square meter (Hh/m²) of executed coating so as to identify among the workforce‟s employment categories chances of improvement. As research strategy, it was used the field survey in five construction works with different types of buildings, where it was made a hard observation and labor productivity collection taking into account the occupation categories (Direct Work, Delays, Mobilization, Downtime, Displacements and Support) resulting in productivity indicators stratified in accordance to these categories. It was diagnosed that the values of the overall workforce‟s productivity ranged between 0.16 and 0.50 Hh/m², considering that the main value in the distribution of its fractions was in the occupation category of Direct Work, which ranged between 0.08 Hh/m² and 0.23 Hh/m² regarding the other categories. The higher the representativeness of main productive and auxiliaries categories (Direct Work, Support and Mobilization) over the categories associated with the unproductive activities (Downtime and Delay), the better the productivity detected, although strong statistical correlation was not observed. Regarding the category Direct Work, the best productivity of labor is achieved in the implementation of the coating on the ceiling over the implementation on the walls. Thereby, this work‟s main contribution is in the preparation of the analytical structure of occupation categories to the plaster coating department as well as the unfolding of workforce‟s productivity indicators in these categories for this department.
