I do not believe that rumor is accurate. There have been rumors floating around for years that the pathology job market is terrible. There was even an email that was being circulated a couple of years ago by some person in Chicago telling medical students not to go into pathology because the job market was so bleak. My PD said that this was a disgruntled FMG who was having a difficult time finding a job himself due to visa or licensing issues, and was trying to make it sound like the sky was falling. I have been told by all of the attendings I have worked with to ignore these rumors, because they are not true.
Just about every field goes through cycles of "waxing and waning" of job opportunities. There may be fewer jobs for a couple of years, and a percieved "glut" of persons going into that specialty. Then medical school graduates stop going into it for a few years because they are concerned about the job market. Then a few more people will retire and suddenly there's a shortage.
I agree with Pathdawg. If you like it, you shouldn't let anyone tell you not to go into it.
