The employee welfare in official educational institutions has been affec- ted by organizational development (OD) and indoor facilities inside the workplace. This research examines OD and indoor facilities variables that hamper teachers’ welfare and job performance, through a study that compares how school employees perceive working conditions and workplace environment within two Colombian educational institutions. During the first phase, a 22-item questionnaire (ODFEI) was designed and administered to full-time teachers (58) to identify their perception of the welfare conditions within the workplace. The first phase involved the description of the variables for each school, whereas the second phase correlated the variables between both institutions, with the pur- pose of developing the comparative analysis using the U Mann Whitney test. The experts validated the data collection instrument, which obtai- ned a Cronbach Alpha of 0.85. Both institutions coincided in a finding that indoor facilities, physical infrastructure, and comfort complements were under poor workplace conditions, which affected teachers’ per- formance. However, it was contradictory that the issues of discomfort regarding the teachers’ work were not disclosed on time, despite the good labor relations manifested by the OD variable. The questionnaire represents a support instrument for managers and teachers because it allows them to verify working conditions in time in order to develop effective strategies that improve the comfort of teachers.
