Page "Ovadia Yosef" Paragraph 52

And I knew clearly when I was in Egypt, that many of these people ( who worked on Shabbat for their livelihood ), when they leave work, are careful not to desecrate the Sabbath, and indeed do not smoke on the Sabbath and all that follows from that.

And some of them pray on the Sabbath in the first minyan so as to get to their workplace on time, and in secret their soul would weep that they are forced to desecrate the Sabbath for their livelihood.
