I agree with Steve.  I've been in the industry for 14 years and rarely do I miss personal events in order to work.  In the few occasions that I've made an exeception, I've missed minor events and I've made certain that it was worth my while financially to miss the events in question.  I can't count the number of managers that I've worked for that have made promised incentives that they didn't deliver.  

In no case would I consider selling out my family just to make an extra buck.
