Answer:
Is interfering with his ability to function effectively.
Step-by-step explanation:
Mental health sometimes can be subjected to subjectivity, however, there are some things in which all mental health professionals agree and it is that, we can say that a behavior is actually abnormal once it starts interfering with the individual ability to function effectively and starts taking a toll in his social and working relations.
In this case, the behavior that Josh is having is finally interfering in his job because he kept being late for his job (because of his need to retrace his steps) and it also made him unable to complete his projects on time.
