Incumbent employees may struggle with a variety of challenges depending on their specific job and industry. However, some common struggles that incumbents may face include:

1. Burnout: Incumbent employees may find themselves feeling overwhelmed, stressed, and burnt out from the demands of their job. This can be due to long working hours, heavy workloads, and a lack of work-life balance.
2. Adapting to change: As companies and industries evolve, incumbent employees may struggle to keep up with the changes and adapt to new ways of working. This can be particularly challenging for those who have been in their roles for a long time and are used to doing things a certain way.
3. Stagnation: Incumbent employees may feel like they have hit a plateau in their career and are no longer growing or advancing. This can lead to feelings of frustration and a lack of motivation.
4. Lack of recognition: Despite their experience and contributions to the company, incumbent employees may feel like their efforts are not being recognized or rewarded. This can lead to a lack of job satisfaction and motivation.
5. Skills gap: As technology and job requirements change, incumbent employees may find that they lack the necessary skills to perform their job effectively. This can make them feel inadequate and anxious about their job security.

It’s important for employers to recognize and address these challenges faced by incumbent employees to maintain a productive and engaged workforce.
