You work for a firm of accountants and your colleague, who is more senior to you, has gone on maternity leave. Your manager has asked you to complete complicated task that your colleague should have completed before going on maternity leave.

You don't feel that you have the relevant experience or knowledge to complete the task, however your manager isn't being very helpful and made you feel uncomfortable when you tried to explain how you felt. You feel there will be repercussions if you do not carry out the task.

Consider what you would do in this situation and the fundamental principles that are involved.
