You should always be "trying". The idea that you corner some obscure but vital part of your company's infra and then just coast is pretty abhorrent to me. Instead, if you find something difficult, complicated and manual, you should make it easy, simple and automated.
I do believe that firing people based on big data analysis is pretty dumb as some tasks require lots of deliberation and thought without much output initially. But the idea of working hard = being dumb, seems like a pretty creative way of justifying being lazy.
