Staff members who contribute a lot to activities and coaching at your school must also spend a lot of time away from home. Send a short note with a gift to the staff member's spouse or significant other recognizing the effort, but also thanking the team at home for their support. This will recognize the patience and understanding that has to occur on the home front.
The Leadership class could offer a babysitting service or pet sitting option to give the couple some time together.
Just letting the person at home know that the contributions to your school community are apprecitated will mean a lot to build and recognize the home support.
