Make sure you’re playing the latest updated version. You get the other endings by activating the heterodox protocol which reveals a link to a message on the wait screen. Clicking that message + testing everyone a lot should cause a new option to appear on the Evaluate screen on the 3rd day. I felt confident that I got the endings working last night for most characters, but there was one report that said the company representative ending was still not working. I’ll continue refining and fixing my mistakes so just keep checking back!
