From my previous life, we have introduced "Absence Return Interviews" and have a clear procedure for employees returning from absent days. There is a questionnaire form for line supervisors/managers to go through so as to avoid the impression of being personal...it's about the procedure, system and company policy and not about the person.
As with any other performance management tools, the form explores contributing factors or what could have been done differently to prevent the person from being absent (if applicable), what could be done next time, how the company can support the individual to improve attendance (e.g. change in roster/change of hours), etc.
This is taken from a collaborative perspective, working with the employees to improve attendance. However, consistent attendance issues will inevitably lead to disciplinary procedure.
In terms of termination, the termination of employment procedure and principles are followed. No one should be dismissed without a chance/opportunity for improvement and having appropriate support/strategies to improve. If you're talking about abandonment of employment, then there are clear standards that should be followed.
Let me know if you want more info.
