It's a job you'd never apply for. But you already do it.

You mightn’t realise it, but there’s a good chance you currently hold a job that others would describe as “illegal” or even “inhumane”.

The hours are limitless, there’s a lot of standing time, lunch breaks are a rare treat and your boss regularly needs you to stay up with them until the wee hours. You need to be adept in cooking, communication and economics – oh, and there’s no pay.

Sound familiar? Congratulations, you must be a parent – and when you break it down like that, it really does sound like the world’s toughest gig.

An ad company in Boston has highlighted this in a new online campaign, in which 24 eager young candidates are interviewed over Skype for a Director of Operations “position” advertised online. Watch as they react with surprise and indignation to the numerous demands of the job – and then smile with recognition as they’re reminded that there’s someone in their life who fulfils this role every single day.

Parents, this one goes out to you.
