Christians in the Workplace

I have been thinking a lot about Christians and their vocations, and I will start by examining some of the texts that I find relevant and throw in some topical discussions based on it. Are there any particular passages or topics that ought to be covered? I was planning to hit up at least the following:

• Genesis 1 - 3
• The story of Joseph
• The Law and its teaching on property and slavery
• The promises in the Pentateuch and the work required in them
• Jesus' teaching on masters and slaves
• Masters and slaves in Ephesians and Colossians
• Service to masters and government in Peter's epistles

So, those are the places to which I am particularly eager to turn, but maybe there are some other such and such as it comes up. I had a list of the topics, but I set it down somewhere and I will have to find it.
