Lead from the front
If the employer is not regular at work and does not handle things in a professional manner, he/she will never be able to reduce absenteeism in the office. If you want your employees to be professional, you have to lead them from the front by setting the right example.
If you do not come to work at the right time and often take days off, you will not have the moral authority to hold your employees accountable.
Online attendance system
Most high-quality organizations have an online attendance system, instead of the employees having to mark their attendance on a paper. By adopting the latest technology, it is going to be very easy for you to keep an eye on your employees.
The modern style of management does not adopt a carrot and stick approach, instead, you should look to motivate your employees to such an extent that they give their hundred percent even when you are not present on top of their heads.
Employees, who come to work regularly throughout the year and are highly dependable, must be rewarded. This will create a very positive competition among the employees in the company.
Similarly, the employees, who are not dependable and are often absent from work, should be penalised, just to make them aware of their non-professionalism. However, firing an employee because of poor attendance should be the last step.
