<p>So the answer in IT (in my experience) is: No, a PhD is not at a disadvantage to a BA/BS and may, depending on his field, have an advantage.</p>
<p>The only possible disadvantage would be in a very highly structured corporation where the posession of the PhD would force him out of the salary-band budgeted for the position. This can sometimes be negotiated, sometimes not.</p>
