You don't punch a clock? Are you at Ground? Falsification is always a termination offense at FedEx unless you're on the favored list. I'm thinking you'd get a warning letter or an OLCC at Express not necessarily termination.
Don't do it and you won't have the problem. You might also want to change your username.
The one time I was late (like 2 minutes), manager said to change my scheduled time to match my start time. Be honest about your mistakes and they may be more lenient towards you.
That's what I'm saying. Why falsify to cover up for something as trivial as being a couple minutes late? Being late once or twice is no big deal. Falsifying on the other hand...
