The BEST way to handle the situation in this scenario is Option 4: Show your coworker how to work faster and offer to help finish the assignment. By doing this, you are not only being proactive in addressing the efficiency difference but also being supportive by offering help and guidance. This approach fosters a positive work environment and promotes teamwork.
The WORST way to handle the situation would be Option 2: Report your coworker's slow performance to your supervisor. This option can lead to strained relationships in the workplace, create unnecessary tension, and could be seen as undermining your coworker instead of trying to support them in improving their skills. It's important to approach such situations with empathy and a willingness to collaborate rather than resorting to punitive actions.
In summary, offering assistance and guidance to your coworker in a supportive manner (Option 4) is the best way to handle the situation, while reporting their slow performance to a supervisor (Option 2) is the worst way to address the issue.
