I also have a job where I have to work most weekends. So far, I have had one Sunday off, where I attended Mass (2 weeks ago), and will be attending this coming Sunday. I will have 3 Sundays off next month. Normally I have to work both Saturday and Sunday. When I have Saturdays off, I can’t go to Mass because my chapel does not hold Mass on Saturdays, and I do not want to attend Mass at a Novus Ordo church. Instead, what I do is do a Holy Hour of Reparation and the Rosary - I was told that that satisfies the obligation of attending Mass on Sundays, when I cannot go. I will also talk to the priest about what he thinks I should do, so I won’t jeopardize my job; I work in the tourism business, and my place of employment is in its very busy season right now.
