You are at another employee's desk helping them solve an issue they reported to the help desk where you work. A few moments after they have explained the issue and you begin troubleshooting your phone begins to ring. What should you do next?
Check the caller ID and answer the phone if it is important
Silence the ringer and apologize for the interruption
Excuse yourself to handle the phone call and return to the employee's desk when finished
Politely excuse yourself and answer the phone, telling the person you will call back later
When working with customers and colleagues you should maintain professionalism and avoid any distractions or interruptions. Silencing the phone and apologizing is the best choice given the scenario. Continuing or escalating the interruption could be seen as rude and interpreted as you not caring about the person's issue.
