Not an engineer. I work with a variety of engineers. Turnover is very low and has been that way for a while. Civil and mechanical engineers mostly supporting the petrochemical industry. When someone does leave or someone is hired it's mostly someone changing to another company that does the same stuff. Jacobs does most of it now since a lot of the jobs are now contracted out post 1981. I knew some engineers for Dow that at one time were temp Kellys girls, that did not go over well. I wouldn't say it's growing, more shifting around. Not petroleum engineers, all these jobs are supporting chemical plants and refineries, who knows going forward with refining and marking subsector of the S&P 500 being up near 50% year to date.
