John C. May is Chairman of the Board of Directors, Chief Executive Officer, Chief Operating Officer and President of Deere & Company sold $72,473 of Deere company stocks a few days before the strike began.

 May became the company’s Chief Executive Officer in November 2019 and assumed the position of Chairman in May 2020. He was named President & Chief Operating Officer earlier in 2019

So I assume he makes all the decisions at Deere, and that includes not meeting the unions strike demands, and opening the door for them to walk out on strike
