There is no "right" answer. There are many answers based on which competing value(s) of many, you interpret as the most important in the situation.
The key here is to gather information/facts. Are there legitimate reasons for the situation (illness, enviroment, side job, etc.)? Once the facts are determined you can evaluate the possible options by weighing the pros and cons of each. Presumably, selecting an option with the most net positive effect.
There's never time to do it right but always time to do it over.
