Part of being a diligent employee is ensuring that you are always on time and present when expected. Your attendance impacts the rest of your team. Showing up early, getting the lay of the land, and warming up before you hit the ground running can shore up your success and that of the team. Showing up late can result in stress, panic, and confusion. It can also overburden others on your team who have to pick up your slack when you are running behind. Lastly, it could speak to your time management and organizational skills, as well as the value you place on your performance.
