Can I ask what country you are in? Because I’m interested when you say publishers need to make up time by contacting inactive ones.
I'm from Northern Illinois, U.S.A. My niece is a pioneer and has never called me in the 9 years I've been inactive. She called me to pad her pioneer hours. She told me that she mails letters and calls on the phone. No house to house in over one year. She has a list of return visits and either calls them or sends them a letter.
So, she called me to see how everyone is and also total the time she spent on the phone with me and add them to her monthly pioneer hours.
