Dear Padma,
If the employee has not corrected his behavior despite receiving the memo twice, then you need to escalate the level of negative discipline. However, do not reach the last option of termination immediately. Impose a penalty on him twice. If he still does not improve his behavior, then you may proceed with termination. However, before termination, it is advisable to conduct a domestic enquiry.
One strikingly odd punishment could be to transfer him to an unrelated department like security. Deny him access to mobile or computer. This may lead him to become frustrated and voluntarily resign. Therefore, no further punishment or termination may be necessary. While this may seem harsh, sometimes such tough measures are required.
Thinking from an HRM perspective: If the employee has time to browse social media, it suggests he has sufficient time available. Have you monitored his performance targets? What is the level of his performance? Is browsing social media impacting his performance? If yes, termination on the grounds of poor performance could be considered.
In many IT companies, employees have complete freedom to access the internet. Despite this freedom, employees are often so busy with work that they do not have time to browse the internet. Therefore, it may be worth considering the performance aspect as well.
Monitoring work closely was common in the past. Rather than monitoring how employees spend their time, modern companies focus on monitoring their performance. To enhance performance, employees need to be well-motivated, which can also be achieved through a proper career plan. Have you designed a suitable career plan for the employee?
Thanks,
