Individuals' search for various opportunities within the context of their job (role opportunity search) is an important yet demanding characteristic of today's work environments. This study tests the effects of harmonious passion and obsessive passion on role tensions (i.e., role conflict and role overload), which is posited to influence the search for new role opportunities. The results of structural equation modeling (GFI = .92; IFI = .90; RMSEA = .07) on survey data from Swedish owner-managers (n = 704) supported that harmonious passion has a negative relationship with role conflict (β = −.14), which in turn has a negative relationship with role opportunity search (β = −.21). This results in a positive, indirect relationship between harmonious passion and role opportunity search. In contrast, the positive relationship between obsessive passion and role conflict (β =.44), results in a negative indirect relationship with role opportunity search. The relationships applied for passion were also applied to role overload (harmonious passion: β = −.26; obsessive passion: β = .41, p < .001), but no significant influence was found from role overload to role opportunity search. This study provides insight into the importance of considering role tension in passion models, especially when explaining role opportunity search. As demonstrated, whether role opportunity search will be facilitated or hindered by passion originates based on whether the passion is harmonious or obsessive.
