When a county officer or employee, without prior authorization, is absent or fails
to discharge his regularly assigned duties for such period of time that it appears
likely he intends to resign pursuant to subsection A of Section 5.12.020, the appointing officer of such affected officer or employee shall service upon that
officer or employee, either personally, by telegraph, or by first class mail addressed
to the most recent address furnished to the appointed officer by the affected officer
or employee, a notice in writing stating that failure of the officer or employee to
resume the discharge of his duties on or before the commencement of the working day
stated therein shall constitute such resignation. Said notice shall be posted, delivered
personally, or delivered to the telegraph office at least 24 hours prior to the commencement
of the working day specified in the notice. Failure to give such written notice shall
not cause such resignation to be ineffective.
