This piece of code:

            if (employees[i].inoffice === true) {
                statusHTML = '<li class="in">';
            } else {
                statusHTML = '<li class="out">';
            }

You're setting the string equal to the <li> tags instead of adding them onto what you have. This erases what was previously written. So just use the += operator.

            if (employees[i].inoffice === true) {
                statusHTML += '<li class="in">';
            } else {
                statusHTML += '<li class="out">';
            }

Additionally, you may want to look into markdown to make your post easier to read. This can help improve your chances of getting an answer.
