So what about folks like me? (I know what my priest has told me, but would love to hear the consensus on here.)
I'm a nurse. I work 12 hr shifts--the only option at the hospital. I have to work every other weekend. So I work from 7am-7:30pm both Sat and Sun. How do I get to mass? Vigil is at 5pm, latest mass is at noon. Can't make either. So what do I do?
If there is no Mass you can possibly make, and you simply do not have an option to change your work arrangements to provide a different schedule, then there is no obligation. I would double check for an obscure Mass, as suggested to you, but if there isn't one, then there isn't one. I don't think anyone here would disagree with the statement that you are then not obligated to attend Mass.
However, the problem presented in the original post was the ambivalence of 'tired' and 'potentially late for work'.Simply knowing that someone is 'tired' and 'potentially late for work' is not enough to go on to say that he is definitely excused from the Sunday obligation, and I think it was unwise for the people at the original board to say so without more information to go on. One easy way to fix 'potentially late for work' may be to stand at the back and leave a little early if need be, and then one has at least tried. 'Tired' may mean something so serious that it does indeed excuse from the Mass obligation, but it very often would not be.
