Congrats on the new job. I worked in Shipping myself and here are a few tips to remember:

1. Learn to drive a forklift if you do not know how already
2. Hone your Math Skills
3. It is better to Print than use cursive
4. Always, Always Triple Check Your Work. Read the order first to clearly understand what it says to avoid confusion later. Pull the order and dbl ck. and last, before you place the invoice on the shipment, dbl ck again.
5. Make sure your aware of all safety procedures
6. Bend at the knees when lifting
7. Always show willingness to help others if it does not interfere with your job first
8. If you see a mistake, bring it to someones attention, It is not a mistake unless it reaches the customer Catch it in-house first before it goes out the door.
9. Do not become offensive when someone catches one of yours, for they are your back up eyes. You are all a team and there is no "I" in TEAM
10. Most importantly...Learn how to Breathe

Hey Eric, Congrats on the new job! Josh makes a good suggestion and I recommend you give that a try but if it’s a package handling position you can expect to be busy from day one. Your body is going to feel the pain of them job no matter how much you prepare but the key thing to remember is that each day your body will condition itself to the demands of the position and the work will get easier, (give it about a month before you notice the difference). Don’t get discouraged because because of the physical demands! Sups and managers understand that it takes time to adjust. Demonstrate a good attitude and volunteer for extra hours when asked any you’ll be a good candidate for F/T employment. Good Luck!!!

Start your walking now fast pace walking with weights if ur lifting and moving stuff good shoes and always do extra even if not asked too or volunteer yourself for projects etc
