I'd beg to differ. Use of incorrect verbiage goes to a mindset. A mindset that includes lack of self discipline which can lead to unprofessional behavior and/or outright disregard for procedures and policies. Yes, that may be taking it to the extreme, but as I originally posted, the Pinnacle crash is a classic example of lack of self discipline and where it can lead.
You have a choice as a professional pilot. You can either be disciplined and do what your company wants or you can choose not to. It's up to you to decide whether it's important to your career.
I guarantee you there are airlines in this world that will hammer incorrect verbiage out of a pilot very quick or they will fail training. Japanese and Korean airlines being prime examples.

3407 sadly is another case where incorrect call outs/verbiage contributed. Once in the recovery, the trained call outs were never used, and the correct recovery procedure was not performed. A very simple ," stalling, check power, flaps 10" would have brought the FO onto the same page. People that are unsure about the correct action normally perform it correctly with the right trigger.
Instead power was never checked, and flaps came up without a command, before the recovery was initiated.
Now, most everything has a "callout". It's not gear, or pop the gear etc. we say ," gear down reduced (or normal) np". This command triggers a flow, and both items refer to a selection. In fact we don't say push, select, or hit at all. Every item like that is a commanded position. Select level 2 icing, props 850, etc. On our side we always state the condition we want selected... Not the actual switch. Because of this, its important to use correct verbiage, or you introduce an element of uncertainty that we have been working our buts off to eliminate.
That being said, I'm not a nazi about it, but, I use correct call outs, and try to push people to do the same. It often only takes a few legs , and they're doing it. If not, a quick," we say it this way, because ...." give an example, and they usually agree.
Recently we renamed all the checklists to agree with switch position labels. It's not " ref speed switch on" it's ref speed switch increase. Etc. this was done to eliminate position uncertainty that some were having. (?). When the wording is correct, the lists just work better. Honestly though, the parts that proper verbiage applied to, is such a small percentage of what gets said, is it really that hard to do it the way your airline wants?
