Calendar Summary Page?

I have a workbook with multiple calendar sheets in it, those sheets are names by the staff member name (attendance calendar). We put the value 'H' or 'S' in the cells to indicate whether an employee is on holiday or sick. I would like to create a summary calendar/dashboard that shows which people are off which days, like a summary or another calendar with names in date cells. I have tried various ways, but cant seem to return the value I want, or find a simpler way of doing it.
