I've tried it on my work computer a couple of times, but mostly I trade with my phone because it's more convenient and I can trade anywhere I'm as long as there's an internet connection. I don't think it's a terrible idea as long as the computer you're using is fully protected and the anti-virus has been updated and you're also making sure you log out whenever you don't use it, especially if the work computer is common to anyone at work to make sure that nobody can use your account.
