Ensure that you arrive on time — or better yet, early.
Driving to work
If you plan on driving, practice driving there a couple of times at the same time you will be heading to work so you can time out the drive, and also plan ahead for any potential traffic issues. Having an alternate route is also a good idea. You need to know more than one way to get to work in case you find yourself stuck in traffic or encountering an unexpected delay.
If taking public transportation is your preferred method, plan out the route ahead of time and have a solid backup plan (bus instead of the train, for instance) just in case.
For those of you bold enough to cycle to work, please leave yourself enough time to change into your uniform. It will be your responsibility to figure out where to store your bicycle.
