Economic conditions that cause reductions in work force, the member’s inability to attend regularly to work, chronic illness, and a failure to perform competently on any of the critical tasks of the position or a consistent failure to perform competently on regular tasks are among the major reasons for job removal without the fault of the jobholder. Failures to support the agency’s mission, uphold the oath of office, behave in a manner that supports the Sheriff’s Office Code of Conduct, continually comply with preconditions for original employment, or display due regard for the civil liberties of any persons will lead to removal with or without fault.
