Is HRM evidence-based and does it matter?

In these respects, HR practitioners are probably no different. Of course what is done is based firmly on evidence, isn’t it? And, there’s plenty of firm evidence around, isn’t there? What about all that CIPD research, the countless books, Dave Ulrich’s stuff, all those journal articles, and, of course, all the research conducted here at IES? To even speculate about whether the work of HR is evidence‐based can just seem plain silly, a little stupid, and even somewhat insulting.
