How to reduce absenteeism in the workplace?

First of all, you as a manager, you have to have an attendance or an absence sheet to hold employees accountable for their attendance and how necessary it is to keep track of it.

Secondly, Make rewards and bonuses for employees for having no absences in the past 12 months period for example.

and third, value your employees by making them feel special in the workplace by supporting them, providing them with adequate paid time-off so they can actually have an option to plan for an absence if necessary.
