Re: Probably some HR or marketing bod
That, and there are also hoops to jump through with photos of real people that you don't have with models. For example, once someone leaves a company they can insist on being removed from any materials, they can also be really fussy on a photoshoot, which you also have to coordinate with them. Also, many people see such publications as aspirational and don't want them full of the dorks from the office next door. Exceptions prove the rule, but, when you're not actually providing interviews, it's best to avoid employee pictures.
But the biggest problem with these days is that they reek of symbolism instead of policy or action.
