It's Labor Day, which means we're celebrating the hard-working people who keep the engines of productivity humming. On this episode, we'll explore how science and technology are changing work and workplaces, and what we are learning about the pitfalls of different work environments. Our current healthcare conundrum certainly stems in part from the coupling of work and insurance benefits — so we'll look at the past and future of this union. We'll meet a woman who used science to prove that ladies should be part of the workforce. Plus, the psychology of snarky office emails, and the case for mandatory vacation days.
