I think the answer to this is actually fairly simple. When the bossman tells me something's in my best interest, I'm just immediately suspicious. Like I know in your example it maybe is, you've laid out your logic and all of that. But you have to realize that for every good boss, there's probably 15 bad ones. Western economic, labour systems and power structures have been so lopsided for generations, that it's literally hard coded in us to be suspicious. Whenever someone comes at me from work with a big smile and excitement, my flags FLY to red alert. Because I'm statistically far more likely to be on the raw side of the deal.
