And also the section in the Catechism
A day of grace and rest from work
2185 On Sundays and other holy days of obligation, the faithful are to refrain from engaging in work or activities that hinder the worship owed to God, the joy proper to the Lord’s Day, the performance of the works of mercy, and the appropriate relaxation of mind and body.123 Family needs or important social service can legitimately excuse from the obligation of Sunday rest. The faithful should see to it that legitimate excuses do not lead to habits prejudicial to religion, family life, and health.
The charity of truth seeks holy leisure- the necessity of charity accepts just work.124
2192 “Sunday . . . is to be observed as the foremost holy day of obligation in the universal Church” (CIC, can. 1246 § 1). “On Sundays and other holy days of obligation the faithful are bound to participate in the Mass” (CIC, can. 1247).
2193 “On Sundays and other holy days of obligation the faithful are bound . . . to abstain from those labors and business concerns which impede the worship to be rendered to God, the joy which is proper to the Lord’s Day, or the proper relaxation of mind and body” (CIC, can. 1247).

and also Pope Benedict XVI document:
"The meaning of rest and of work
- Finally, it is particularly urgent nowadays to remember that the day of the Lord is also a day of rest from work. It is greatly to be hoped that this fact will also be recognized by civil society, so that individuals can be permitted to refrain from work without being penalized. Christians, not without reference to the meaning of the Sabbath in the Jewish tradition, have seen in the Lord’s Day a day of rest from their daily exertions. This is highly significant, for it relativizes work and directs it to the person: work is for man and not man for work. It is easy to see how this actually protects men and women, emancipating them from a possible form of enslavement. As I have had occasion to say, “work is of fundamental importance to the fulfilment of the human being and to the development of society. Thus, it must always be organized and carried out with full respect for human dignity and must always serve the common good. At the same time, it is indispensable that people not allow themselves to be enslaved by work or to idolize it, claiming to find in it the ultimate and definitive meaning of life.” (209) It is on the day consecrated to God that men and women come to understand the meaning of their lives and also of their work."
