Interest in the field of emotions in the workplace continues to grow. However, a narrow range of measurements exists for the examination of affective states in organizational settings, all of which were developed based on the discrete-emotions approach. The main objective of the current study was to develop and validate a new instrument to assess four work-related (WR) affective feelings (WORAF): WR feelings of happiness, WR feelings of anxiety, WR feelings of anger, and WR feelings of dejection. Three independent samples of Polish employees in different occupations were included in the study (n = 297, n = 3019, n = 284). The results provide significant evidence for the validity of the proposed WORAF scale, although further investigations are needed.
