Want to get away? It's not easy in investment banking, but William Blair makes the effort. That's what its bankers said in the Banking 50 survey. The firm again ranked #1 -- more than .65 of a point better than the nearest competitor. That said, the firm actually lost serious ground in this area...nearly .5 of a point. That said, both Centerview Partners, Lazard, Peter J. Solomon and Morgan made major strides when it comes to honoring time off this year, with Evercore and Bank of America losing a little ground in the process.
