Some employees habitually arrive late daily.

Question

Some employees habitually arrive late daily. However, they also leave late. For example, he arrives 10 minutes late daily. But also leaves 20 minutes late daily. Other employees arrive late daily, then work extra hours on another day, far beyond their time late coming. Although their time is made up, it is inconvenient as they not available for meetings, etc. in the morning and people call for them and they are not here. Furthermore, they have NOT discussed this with their manager where they will work late to compensate for late coming. Is it permissible to deduct late-coming time based on the wage amount even if they are making up the time later unilaterally without company permission?
