I just got an offer to interview for a position that would be a promotion with another company. Your hang up is clearly not an issue for your competition. So, if you want to retain someone you admit is one of your most valuable employees, who says she DOESN'T want to leave, you might want to change your tune from "We have to take your only shift away (again), but PLEASE don't leave" and "Unless you can do (blank) you have no future here." to something more appealing. Because, while I know amazing management when I see it, and am willing to stay because it's so rare; I also know my own value, and there are limits to my willingness to compromise.
