Quote From wj_gibson:
I'm sure you have indeed been through some of this, Sneaks, but you need to appreciate that to do what you suggest requires me really to think about leaving my job, which is a professional, 9-5 endeavour (often more hours than 9-5, in honesty) and which requires me to work hard and is thus intellectually difficult. Guest lecturing is out of the question in those circumstances, and it's very hard to really finish any writing off unless I more or less give up my other outisde interests in life entirely and spend all of my time outside work on it. I've had my CV checked over by a few acdemics and other than some tweaking they can't see anything wrong with it.
I understand your predicament. I think guest lecturing i.e. 1 lecture per term would surely be doable though - just a day off work, you could use your holiday time, or convince your boss its part of your professional development.
In terms of the CV, I really would consider having someone non-academic check it out. you should be thinking about adapting your CV for each job, so you highlight the skills they are looking for. And not only listing jobs, but pulling out the skills you have learnt from them, really smacking the reader in the face with stuff you may have assumed they already know.
if you have had 142 applications and no interviews, it will be your CV!
