It's a big responsibility. People step down from demanding church assignments all the time and are often given a "thank you for all your service" party.
LOL If JWs did that there would be no Elders or MS so instead they use fear, obligation and guilt. They want you to be afraid of what others will think when the announcement is made from the platform. They want you to feel obligated to the Elders to continue whatever responsibilities you currently handle. Of course guilt is used to make you feel like you're not giving enough to Jehovah.
