A boundaryless career is not necessarily limited or focused on a single organization. This is in contrast to the traditional career, largely defined or bounded by a single employer. A career can be considered boundaryless in one of two ways: physical or psychological. While many people are both physically and psychologically boundaryless in how they pursue their careers, it is possible to be one and not the other.

The most visible aspect of a boundaryless career is the physical dimension. Someone who pursues a physically boundaryless career engages in a higher level of mobility than someone in a traditional career. Physically boundaryless workers use their job mobility as a method for achieving growth and personal goals, as opposed to wayward individuals who have many jobs because they lack the ability to maintain one. However, individuals are not required to change employers in order to pursue a boundaryless career.
