UNFAIR TREATMENT OF EMPLOYEES
Scrooge is shown to treat his clerk unfairly, providing him with a very small fire and keeping the coal-box in his own room, threatening to part with the clerk if he tries to replenish the fire. This demonstrates a lack of concern for the clerk's comfort and well-being.
SCROOGE
Scrooge had a very small fire, but the clerk's fire was so very much smaller that it looked like one coal. But he couldn't replenish it, for Scrooge kept the coal-box in his own room; and so surely as the clerk came in with the shovel, the master predicted that it would be necessary for them to part.
