Being a Swing Driver is a good position as long as you are willing to work whenever they need you - you can potentially get a lot of hours. The key to success as a Swing Driver and as a Courier at Express in general is not getting into an accident - it has nothing to do with having lates. Any day you return to the building not having had an accident is a good day. Don't let anything they tell you about your on-road performance with SPH, gaps, etc. change your safe driving and use of best practices. They try to say these things/present you with reports to make a courier think they need to go faster - but usually don't say that they need to go faster, so don't go faster. But if they ever tell you that you need to go faster or even if they just question anything you are doing, request a checkride and also that a manager runs the route with you in the passenger seat. Above all the things they will tell you about performance, make sure you have control of your own emotions out there, stay cool-headed - I'm talking about with having lates. You will have lates. When you're on a route don't speed/run or get frustrated just because you have lates. As long as you didn't get in an accident you're fine. If you want to go above and beyond for the company as well as yourself, don't get into an accident. If they question you about your performance, request a checkride and that they run your route with you in the passenger seat. Perform each and every time on road as if you are being given a checkride.
