Positional tolerance question

Not looking for a doctorial thesis on mechanical tolerancing, just an
opinion. We're machining fairly low-tolerance mechanical parts. A
machinist disciplined for not checking holes ultimately discovered to
be off the center-line ~.025 makes the somewhat weak point that there
was "...no dimension, so what's the tolerance?!"

Cylindrical part
Cross hole (pictorially on CL) 1.000" from end

In your typical "three place means +/-.005" situation is location
tolerance about the CL a function of the OD, .875 in this case, thus
+/-.005,...or even perhaps +/-.0025 ?

E-mail is fine, thanks
