If you are in the mid-Atlantic region, you might want to check out the Gospel at Work conference. The goal of the conference is "to promote a biblical, healthy theology and practical application of work that seeks God's glory, the good of others, and our own joy."
9Marks speakers doing plenary talks include Mark Dever ("Work as Worship") and Michael Lawrence ("A Theology of Work"). Os Guiness ("The New Christian Renaissance"), Bob Doll ("Work as Discipleship"), and Eric Simmons ("Work as Faithfulness") are also giving plenaries.
And I will do a breakout session on authority, how to work for a bad boss, and how to be a good boss.
