At what stage in their careers do problem employees typically manifest their behaviors?

Problem employees can manifest their behaviors at any stage of employment due to a variety of factors including personal circumstances, professional growth, peer influences, or changes in work environment. These behaviors are not limited to a specific phase in a person's career; instead, they can arise early on during training or later after years of service. Employee behavior is influenced by a complex interplay of individual characteristics, job expectations, and external pressures, which means that issues can surface at any point. Recognizing that problematic behaviors can develop at various stages enables supervisors to be vigilant and proactive in addressing these issues as they arise, irrespective of the employee's tenure or position within the organization.
