This is chronological
Babysitter;
Social Worker (specializing in obtaining services for the disabled); and
Translator, my current profession, and the one I will probably have until my dying day.
Throughout my life, I have also volunteered extensively, and of course, for the past eighteen years I have had the great pleasure and agony of being a mother.

Chronologically:
- babysitter
- concession stand cashier
- clothing store cashier
- restaurant busser, then cashier
- office assistant (two different depts. in college)
- housecleaner
- bakery cashier, then sandwich maker, then asst. mgr.
- music library assistant
- office temp
- publishing assistant (subsidiary rights and marketing)
- department store sales associate
- research assistant
- English instructor
- hotel desk clerk, then asst. manager
- art gallery assistant
- college test prep coach
- cocktail waitress
- freelance music reviewer
- photography assistant and office manager
- copywriter/proofreader (insurance marketing)
- freelance writer and editor
- publications/book editor (museum publishing)

...I think that's it!

Roughly chronological:
Math tutor (my least favorite job);
Temp (longest position: X-ray clerk. Most interesting: counting garbage cans for the city);
Math grader;
Desk clerk/receptionist for community activity center;
Engineering grader;
Engineering research assistant;
Engineer.

Forgot to say that Math grader/desk clerk/engineering grader were all simultaneous. Yay working 20 hours a week and taking 16-18 credits of classes!

I'm not going to list mine (pretty run-of-the-mill, really), I'll just tell you what I wish I could say when someone at a cocktail party asks me what I do:

Most jobs have been concurrent where I have worked at least two at the same time. I am still part-time at the urban public library reference branch and I am starting to think I may be here long-term (by far it is the best, and best-paying, job I have had). I also can't seem to lose these darn kids - I don't know where they keep popping out of! I can tell I am getting old because I am now suddenly aware that I can retire in less than twenty years. Wow, that is incredible to me.

I recently updated my resume to include 2006 Time Person of the Year. I encourage you all to do the same.

Chronologically:

- Photo lab clerk/camera-store salesperson
- Telemarketer (for one day... couldn't hack it)
- Cashier supervisor at a drugstore
... Pharmacy technician at the same chain
- Phone-book deliverer
- Produce clerk at historic market (for only one day... I never figured out why they didn't keep me.)
- Seasonal Wal-Mart floor "associate" (Pets, plants & seasonal!)
- Seasonal gift-shop clerk in tourist trap
... Seasonal movie-theatre clerk in aforementioned tourist trap (I made $5.50/hour but I swear this might have been my best job ever. Total solitude, fall weather and little responsibility beyond rewinding and re-starting a videotape about the site.)
- Seasonal Wal-Mart cashier/customer-service-desk clerk
- Resort hotel housekeeping room attendant (later, houseman)
- Real-estate agency receptionist
- Large-scale photo lab Quality Assurance inspector (same company that I worked for on the retail level back in high school)
- Paintball-factory worker (mostly packaging)
- Freelance Web developer
- Web developer for two failed start-ups
- Data-entry-company clerk (organized/prioritized the stuff for the data-entry people to enter)
- Office clerk in non-profit agency working with people in conflict with the law (or at risk) and their families
- Assistant marketing coordinator at a restaurant-marketing firm (basically I was the person who harasses you after you fill out a restaurant feedback card)
- Receptionist at a university faculty office
... Promoted to Assistant to the directors of two different departments (job description is complex but involved purchasing, payroll and HR aspects on top of mundane admin stuff and department communications [Website, calendar copy, policies...].) It was made into two full-time jobs after I left.
- Music writer
- Office temp (quit my secure union job to do this and it was incredibly liberating)
- Scriptwriter (well, technically scénariste) at a video-game company

I've also run a Web community since 2002. We have about 14,000 members I think. But that's a voluntary thing and the site is non-profit (no ads, member-supported).

Oh, crap. I forgot...

- Before paintball factory, I worked in the same photo lab in the digital alterations-and-restorations shop

- Before scriptwriter, I was a freelance proofreader (got the gig from a MeFite!)

Annnnnnnnnnnnnnd.... now that I've said all that, let me also note that I'm looking for a job! Hint!

Oh CRAP! I can't believe I forgot THIS! I was just thinking about it before I sat down at my computer, too.

My second job was:

- Naval reservist. Technically, an "Ordinary Seaman". Snicker if you must. I was a basic-training dropout.

(I find this my most interesting one, because it's so random and SO UNLIKE ME. But I think discipline, though dreadful, is something I intuitively know I need, and also, I liked the uniforms. It was a fascinating experience that I'm crazy glad I'll never have again. I have tonnes of memories and stories.

I only signed on after I'd ascertained that the only way I'd ever be forced into combat is if someone attacked Canada's shores. I believe that to be pretty unlikely.)

I, too, fear, and crave, discipline.

A couple addenda for my list: between "cultural ambassador" and "stock boy" should be "graphic designer" and "failed entrepreneur."

I'm late to this:

-Picking up golf balls on driving range.
-Chicken cook at KFC.
-Fuel transfer engineer (pumped gas).
-Busboy at Harbor House restaurant.
-Dishwasher at Whistle Stop restaurant.
-Cook at Wendy's (lasted about 2 days).
-Busboy at Darryl's restaurant (lasted about 2 days).
-Printing press operator at Speedy Printing.
-Library page (book shelver).
-Library Assistant.
-Grad student assistant in Special Collections Library.
-Researcher for a railroad company.
-Assistant to Rare Books Curator at Special Collections Library.
-Archivist.
-Records Management Analyst!

-newspaper deliverer
-box office ticket seller at old-timey theatre
-babysitter
-cold line/prep at trattoria
-camp counselor
-library page
-camp counselor, camp counselor, camp counselor
-overnight editorial assistant at newspaper
