Passage One
Miss Susan Brown is 25 years old and has been a night nurse at a hospital since last April. She works 8 night on 6 nights off from 9:15 at night to 8:00 o'clock the next morning. She worked as an office cleaner before she came to the hospital, for she hadn't enjoyed that experience at all. It perhaps is surprising that Susan chose to work at night permanently. She felt she needed a change for one thing, and for another, she hoped to eventually to be come a head nurse. She has also found that a night nurse's work is physically less demanding that a cleaner's, and she can sleep 8 hours during the day. Of course, there are some problems in her daily life. The most serious problem is the headache she get from the dim lighting in the hospital. She doesn't have time to wash her long hair for 8 working days and she has to learn to pack all her social activities into 6 days out of a fortnight. But on the whole, she feels very happy.
