This is not daily labor, or labor for money. If you move on Sunday with the help of your father and brother, you will be saving your mother a great deal of trouble. It would be a shame if the men said “Oh, no, we mustn’t work on Sunday, that would be a sin,” and then, feeling very self-righteous, they settled down to watch the football game on TV, while Mom gets stuck with the heavy lifting later that week.

Luke 13:10-17 New Revised Standard Version Catholic Edition
Jesus Heals a Crippled Woman
Now he was teaching in one of the synagogues on the sabbath. And just then there appeared a woman with a spirit that had crippled her for eighteen years. She was bent over and was quite unable to stand up straight. When Jesus saw her, he called her over and said, “Woman, you are set free from your ailment.” When he laid his hands on her, immediately she stood up straight and began praising God. But the leader of the synagogue, indignant because Jesus had cured on the sabbath, kept saying to the crowd, “There are six days on which work ought to be done; come on those days and be cured, and not on the sabbath day.” But the Lord answered him and said, “You hypocrites! Does not each of you on the sabbath untie his ox or his donkey from the manger, and lead it away to give it water? And ought not this woman, a daughter of Abraham whom Satan bound for eighteen long years, be set free from this bondage on the sabbath day?” When he said this, all his opponents were put to shame; and the entire crowd was rejoicing at all the wonderful things that he was doing.
These paragraphs from the CCC may be helpful as well (the bold emphasis is mine):
2172 God’s action is the model for human action. If God “rested and was refreshed” on the seventh day, man too ought to “rest” and should let others, especially the poor, “be refreshed.” The sabbath brings everyday work to a halt and provides a respite.** It is a day of protest against the servitude of work and the worship of money.**
2173 The Gospel reports many incidents when Jesus was accused of violating the sabbath law. But Jesus never fails to respect the holiness of this day. He gives this law its authentic and authoritative interpretation: “The sabbath was made for man, not man for the sabbath.” With compassion, Christ declares the sabbath for doing good rather than harm, for saving life rather than killing. The sabbath is the day of the Lord of mercies and a day to honor God. “The Son of Man is lord even of the sabbath.”
