Work Related Interruptions
Someone may interrupt you to ask a work-related question or to make a comment about your work. If you are in the middle of a task and someone interrupts you for work-related reasons, you need to stop what you are doing and respond to them. 

How long should a co-worker wait for your assistance? Every situation is different, so there is no perfect rule. In
most cases, you should not make a co-worker wait for
longer than 5 minutes. Think about it from your perspective, how would you feel if you asked a co-worker for help, and then you had to wait for an hour? Wouldn’t that make you feel frustrated?
