Topics

• Becoming part of the workforce

• Trends in employment openings

• Where do astronomers work?

• The changing AAS

Rule Number 1

• Only YOU, the job seeker, is responsible for finding a job, not me, not “the world,” not your mom…YOU!– Resume databases provide a false sense of

active searching– Passive application is useless– You must stand out to get hired– Customize everything job by job

The AAS is here to help

• Job Centers at every meeting

• Career workshops at winter meetings

• Sessions and speakers on career issues

• Networking opportunities galore

• Newsletter articles on employment issues

• Non-academic career information

• Advocates on career issues
