Online Ad for Single Position with e-Flier - Same features as our online ad, but includes our popular discipline-specific e-Flier option. e-Fliers are sent about every three weeks to targeted audiences based on the categories and fields you have selected for your job description. Your job announcement appears in the e-Fliers for the duration of your posting. Typically, e-Flier jobs are viewed nearly twice as often as on-line job postings alone. If the ad is for multiple positions, you must also include the upgrade to the multiple position posting.
