What should Emma do when she realizes she cannot complete her projects on time?

When Emma realizes she cannot complete her projects on time, the most effective action is to discuss the problem with her supervisor. This approach demonstrates responsibility and professionalism. By communicating with her supervisor, Emma can explain her situation, seek guidance, and potentially negotiate extensions or adjustments to the deadlines. It also opens the door for the supervisor to reallocate resources or provide support that could help Emma meet her obligations.

Collaborating with her supervisor ensures that everyone is aware of the challenges she is facing and can work together to find a resolution. This proactive communication is key in a workplace, as it fosters teamwork and transparency. The other options, while they may seem practical, do not prioritize the communication and collaboration necessary for a professional environment.
