The goal of this study was to explore workers' profiles according to the fluidity of their boundary between work and nonwork roles, their motivation at work, and their well-being. A sample of 200 workers completed measures of work-nonwork role blurring, motivation at work, and psychological well-being. Results of latent profile analysis revealed five profiles of workers presenting various combinations of autonomous motivation, controlled motivation, amotivation, work-nonwork role blurring, and well-being. The profiles showed that diverse levels of role blurring can coexist with diverse levels of well-being. None of the profiles associated high role blurring with low well-being. Across profiles, autonomous motivation appeared to be most consistently proportional to well-being, whereas high amotivation or low overall motivation tended to present in conjunction with low well-being. The results are discussed in light of self-determination, border, and boundary theories.
