What is to be done about employees who cannot adhere to a schedule?
In some cases, these problems are due to a blasé attitude or a lack of care, consideration, or diligence. If so, then there is no substitute for constant reminders in your regular one-on-ones.
But sometimes it’s not a lack of care, but rather a lack of skills and habits. You might be the first person to hold them accountable for being “on time.” In the process, you might end up doing this person a huge favor. Many employees will be genuinely grateful for your helping them get better at living by a schedule.
