You really can't just approach your boss and say something like, "Excuse me, Mr. Slate, but I don't know if you've noticed... I've been 10 minutes early to work everyday this month." You would probably be perceived as kissing up and maybe even lose points with such an approach. So how will you use Daily Commute to win some points? Below is a reasonable approach that very well may get you that recognition that you deserve.
1. Use Daily Commute consistently for a month in order to collect some solid supporting data.
2. Take some screen shots of your results that highlight the fact that you are arriving a little bit early each morning.
3. Now, approach your boss armed with your data. You'll want to say something like, "Excuse me, Mr. Slate. I have an idea that I would like to share with you if you have a moment. You see, I've been using this really helpful iPhone app called Daily Commute that I downloaded for free from the app store. The app has some really great features that make my morning commute more predictable. As you can see, by using it, I'm consistently arriving to work several minutes early each morning. I'm less stressed, more efficient, and more productive. I thought that you might want to mention the app at our next staff meeting so that everyone might use it."
You've likely just managed to direct your boss' attention to the fact that you are showing up early consistently. You've also demonstrated the initiative to share your positive results in a way that could potentially really help the company. Get ready for that promotion!
