Have people used this term in your work lately?
Disagree and commit It's a cult phrase and it is actively making me mad because this is what it means to me.
Disagree and submit (to what others say)
Disagree and ignore (the fuckup that is coming because ignoring objections)
Disagree and seethe (over the lack of autonomy and input)
The term is used as a bludgeon to overlook personal and professional issues and allow for those in power to avoid diving into and deconstructing the issue. Conflict is naturally going to occur and you/we need to work through it. This phrase use postpones that and only build more pressure on a future blowup.
I think phrases like this are getting magically imbued with authority and relevancy because hey company ($$$) did it and look at their financial success and ignore that initiative and autonomy are what brought them to that point not this coercive mentality.
