Pick, it might seem not ethical to you but, in the end, you do have to watch out for numero uno (and the family), which is one's self. I would imagine the other gig paid more and that's why he chose not to go with DIY as its executive director. It happens! You do have to, at least, pay the bills to keep a roof over your head and the electric/cooking gas on. Anything extra is gravy (i.e.: vehicle replacement, kid needs braces, family vacation to Baltimore, etc.). You cannot fault a guy for simply going for top dollar elsewhere.
It happened to me in late 2004: Either take a JOB with a major cable provider, which I accepted (and which would have had me commute to Delaware on a daily basis) or go with a CAREER change into auto insurance claims that paid more, that was closer, and gave me the opportunity to obtain certain goals. After accepting the Delaware job, I was offered the claims job. I took that offer to the cable people who couldn't match the offer, so I politely told them of my decision.
In fact, the money (and schedule) is why I left this fine biz back in 1999. I realised, at one point, if I were to make a go of radio, I'd be living in an efficiency and poaching off of Mommy and Daddy for beer/cigarette money. What I was given in my new position (at the time) was the ability to get a one bedroom apartment with enough left over to afford to pay the bills and have enough from that to stock the fridge and take that occasional trip down-a-shore.
It's all about earning top dollar in this day and age, not scraping by and being, as the one commercial says "one lost paycheck away from financial disaster".
