well said SAWB, but which side of that stick do you come from?
Have you ever worked for a bad manager who was a tech first (I have, some of the biggest crooks I ever met) or a good manager who was not a tech? how about a bad manger who was not a tech? what makes a manager or a tech "good" or bad in your opinions ("your" being generic, I am not picking on anyone, and I am asking the question of anyone who reads this)
The pressures a manager faces is considerably different than the demands on a tech. neither is an breeze, and both take great personal integrity to do correctly, imho.
