Easy for you to say. Machinists aren't a commodity, you don't get a
replacement from MSC. Presumably the guy you just fired was doing an
acceptable or better job or he wouldn't be there. Will his replacement
be as good? Better a known devil than an unknown one, if you can find a
way to work with the known one.
