This is an issue I am particularly on top of, as staff retention problems are usually a more significant driver of demand for consulting hires than actual growth of a consulting business (and so an understanding of this is key to the Top-Consultant business).Deteriorating staff retention rates are a major problem across the consulting industry right now, so I would not say that what you are seeing is in any way abnormal ibuprofen. In the peak / boom years a 25% staff attrition rate was not uncommon - so a quarter of all consulting staff moving on each year and needing to be replaced just for the firm to stand still was quite the norm. Contrast this with revenue growth rates of 10-15% (some of which would have been being achieved through rises in billable rates) and you can see that staff churn in a boom is the biggest contributor to hiring demand.In a harsh downturn - and certainly in the market we've seen from late 2008 to early 2010 - this attrition rate plummets to only a few percent. Growth of firms collapses (or even turns negative), but the single biggest contributor to the lack of jobs out there is actually the dwindling need for firms to replace staff who are moving on.To come full circle to your original question, this situation has now been almost fully reversed. The major firms are now seeing staff attrition rates back up at 15-20%, so even though the industry as a whole is not growing a great deal this year there is a major increase in hiring needed just for firms to stand still.The really interesting dynamic in the current market is that firms' margins have been really squeezed, so none have been able to afford generous across-the-board pay rises to try and stem the rising staff attrition rates. The impact on the bottom line would simply be too great. But finding themselves unable to staff projects that are being won (especially in FS), firms are now willing to up the ante very significantly to entice in suitable new hires. And so for those able to secure a move there is the very real prospect of securing a sizeable remuneration gain that those staying put are simply not achieving. Which as word spreads of course makes the likelihood of more people leaving grow; and the resulting number of jobs out there grow too.The trade-off as I see it then is between the prospect of achieving a significant pay hike right now by moving... and the potential that your career path may be rewarded by staying put and showing loyalty to your employer. Not an easy call and obviously very dependent on where you are right now and how likely it is that this loyalty is likely to be rewarded...Tony RestellTop-Consultant.com
