In an increasingly dynamic world, in the field of organizational psychology,it is necessary to understand how individuals have dealt with professional changesthroughout their lives. This research was divided into two studies. The first aimedto test the invariability of the Career Adapt-Abilities Scale (CAAS) in the periodbefore and during the pandemic. The survey had data collected from 2018 to 2022and was composed of 2,674 participants, between 17 and 76 years old, of which 62.4 percent are women and more than 70 percent have incomplete higher education. The datashowed the invariance of the CAAS. The fit indices obtained for both groups,without distinction, were qui(246) = 4037.38, CFI = 0.951, TLI = 0.945, RMSEA =0.07 [0.074 - 0.078], SRMR = 0.038, Gamma-Hat = 0.871. This study concludedthat both the CAAS and the four dimensions separately - concern, control, curiosityand confidence - are invariant measures. The second article analyzed how muchpersonal characteristics (the four dimensions of career adaptability) explain workredesign (proactive actions on the part of the individual) and if there is any specificaspect with greater impact in this relationship. Participated 299 workers, whoanswered a sociodemographic questionnaire, CAAS and Work RedesignPerception Scale. Network and regression analyzes indicated a strong associationbetween concern, control, curiosity and trust and relationship redesign, taskredesign and cognitive redesign. Although all relationships were positive, curiositystood out as the factor that most influenced the redesign of the work. This studycontributes to the understanding of the intimate relationships among careeradaptability and the three forms of redesign.
