Job Description: House Manager

Hello Tessiturians! I was wondering if anyone out there has a current House Manager job description from their organization that they would be willing to share? As part of the New Year, we are updating our old job descriptions, and I am having a hard time finding House Manager (verses Front of House Manager) specific job descriptions. For clarification, our organization specifically sees the House Manager as one who oversees the day of performance lobby operations. So, volunteer ushers (not coordination/scheduling of) and training, audience load in and out, emergency procedures, and light housekeeping duties; and not concessions or souvenirs handling. We anticipate having a separate Front of House Manager that would oversee our House Managers. Anyone with similar expectations? Thank you in advance for your help!
