Here is what the self-appointed "faithful slave said in the Watchtower July 1 1943:
"And for company publishers he [Jesus] says, ’Let us make a quota of 60 hours and 12 back-calls and at least one study a week for each publisher.’ These directions come to us from the Lord through his established agency directing what is required of us; and, for those who really love the Lord and are guided by his counsel, that is a reasonable service requirement. This expression of the Lord’s will should be the end of all controversy. It is for your good that these requirements are made; for thereby you are enabled to prove your integrity and magnify the Lord’s name." https://drive.google.com/file/d/1DnWLlxCIeLhM7Ng75QAetqSR5OO5DrSE/view
Here is what the self-appointed "faithful slave" said 80 years later:
"Beginning November 1, 2023, congregation publishers will no longer be asked to report the amount of time they spend in the ministry. Nor will publishers be asked to report their placements, the videos they show, or return visits." (back-calls)
