Directing traffic is harder than people think. I believe the website downplays your key responsibilities quite a bit. If you are ready to stand in the middle of traffic and risk being hit by vehicles and take the responsibility of others lives into your own hands, then this is the job for you. Its not meant for everyone. Be prepared to stand all day in every weather element including the freezing cold. I hope you have a big bladder because 98% of the time, you don't get to go to the bathroom.
So if you are ready for an extreme mental demanding job, apply here!
