Hello, I'm in the HR Operations department at an IT Company. We have a probation rule similar to other companies, and during that period, we do not allow any paid leave. Many of my employees are taking multiple leaves, around 4-5 leaves every month, citing health reasons. Although I deduct their salary for the leave, it does not seem to deter them. Since their performance is good, we are unable to terminate them. What actions should be taken to address this indiscipline?
