@Wizzer249,
My advice.
1) Be patient, be understanding, be fair. We are all stressed and your employees are no different. Be the boss that you would want to work for.
2) Draw a line, put it in writing, what the expectations are and what you are willing to give. Put the offer for more hours in writing (hopefully this is a public offer that everyone is aware of). Your duty is to provide a fair working environment that treats your employees well as employees. Whatever you offer to one person you should offer to all of your employees.
3) You are not a psychotherapist (I assume). You are this employees financial adviser. Be fair and compassionate as a boss. There is nothing more that you can do that would be appropriate or expected.
