I find myself saying this over and over when responding to posts in this forum, mostly to those of you who are having a hard time getting a job in a library, which I think represents a plurality of posts in this forum.
The odds are stacked against any recent MLIS grad, anyone looking to re-enter the field after a period of time off, and anyone looking for a library assistant/clerk job. That's the simple math of our field: For whatever reason - vocational awe; the perception of libraries being higher-status employers; candidates' misperceptions of what library work is really like; and (IMO) above all the ALA's criminally lax approach to accreditation which has resulted in too many programs, too many admitted students, and too many graduates - there are many more people who want a job in a library than there are available jobs.
Most of you who are struggling to find work either didn't do your homework on the labor market beforehand, or if you did, you convinced yourself that you were going to somehow beat the odds, and now the bill is coming due.
There's at least one thing every prospective and current MLIS student, and every graduate who is trying to land a library job, needs to be doing that most of you haven't done is to have a backup plan: A rough idea of what else besides library work that you could do professionally with your skills in case you don't win the lottery and get the job you're looking for. This needs to be something that is realistic given your life constraints - in particular, your geographical constraints (i.e. a job that's available in your commuting area, if you can't relocate). You need a second version of your cover letter and resume that communicates to non-library employers skills that they recognize and understand - NOT reference, cataloging, reader's advisory, youth services, or anything else library-specific. Non-library employers don't know what any of that means and they don't care. It's your job to demonstrate to them that you meet their requirements using their language, not library-speak.
This is going to look different for each of you based on your educational background, skills, work experience, and location. If you're looking to be spoon-fed a list of options for your plan B, I'm not going to be able to provide that for you. I always recommend O*NET as a great source of data for outlook and pay for different professions: https://www.onetonline.org/. What i can tell you is that there are many MLIS holders across the US who have decently-paid, more-or-less fulfilling careers outside libraries. You can too.
Lastly, i see a lot of AI nihilism on reddit, by which i mean "AI is going to take everyone's jobs anyway so all careers are equally f***ed and it doesn't matter what i go to school for." This attitude may make you feel better about justifying your misguided life choices but it is not going to be a recipe for a good career outcome for you.
