Longest with one company was 8 years, rest of them were 3 years and less ( a lot of them were only for 1 year), but when I was younger I worked for the same person for 15 years. Every time he went to a new company he took me with him. He used to complain about how difficult I was to manage, but someone reminded him that he didn’t have to hire me.
I get bored easily.
I was 22 1/2 years at my prior company and never would have left, but I was downsized. The other day, I celebrated 13 1/2 years at my current job.
I had a job of 1 year before the 22 year job. I had planned for 22 years to retire at 60 when my 35 year anniversary would have maxed out my pension, but, obviously, that plan changed.
I joke, sort of, that my millenial D, who is 28, has had more jobs since she graduated college in 2014 than I have had since I finished my education (law school) in 1983. My D taught for one year, had a volunteer internship for the next, worked as an itinerant special ed teacher for another year, spent 2 years with an educational tech company and has now been with another tech company, health related, for 2 years and a few months.
I am in my 29th year with same employer and 17th year in one of my P/T employment positions. Finished 2 Bachelor degrees during the same timeframe.
My sister and I were just talking about that last night - seems generational. - My mom always seems puzzled when I want to look for a new job at work (same company, but you know). I think it’s puzzling to her who has always done the same thing. (once at a place for 25 years and then at a place for 20 after the first closed down). I can only imagine how puzzled she’d seem if I were looking at all these different roles/departments at different companies each time. 
D1 has been in the same company and same department since she graduated 9 years ago. I think I have been at 6 jobs by then.
I had a 15 year streak, then 17.
Same with my dad who worked in banking most of his career, just changing the name on the building with acquisitions. Early on, he frowned and asked how DH and I planned to end up with any pension if we kept “hopping around.” I would try to explain that people in our industry were funding their own retirements, not working for pensions, but he’d just shake his head. Until he realized that, at 28, I was making much more than he was.
I am still at my first job out of college, 21+ years later. It’s a small office and there have been a variety of people come and go, but the core group from the time of my hire are long-termers for sure. One retired at 63 years of service, one at about 43, and the two remaining are at over 40 years.
I spent most of 18 years with one place (I say most of bc I got a year off to go to grad school and I quit and worked elsewhere for about 6 months during that time). I’ve been at my current employer for 14 years. I will likely retire from this place next year, at 15 years.
38 years. Hospital pharmacist. 3 years retail prior to that and I fled that nonsense as soon as I could! Loved hospital pharmacy professionally, came to hate the job eventually as our community acute care institution got swallowed up by a corporation more interesed in money than health and lives.
Congrats @fendergirl I think any job longer than five years, is a significant achievement!
I’ve been with the same federal agency for 29 years. I’ve worked in a couple of different components of it over the years.
I’ve been in my current group for 19 years.
In my 20s I had opportunities to travel and adventure, and took advantage of them, getting an RN along the way, with many diverse jos, after a lot of undergrad time that never amounted to a degree. Nursing concerned me, as I’d have to stick around a job for a year or two. Fast forward, have been with my current employer for 36 years next month, through mergers and acquisitions. As mentioned above, what was once a lovely community oriented institution that cared about employees and did a great job of building community, is now part of a larger corporation with less heart and soul. What has happened to the American workplace?
I’ve been at my current job for 27 years this month. I will retire with this company in about 5 1/2 years.
21 years in our home business. 
DH and I were laid off multiple times in the '90s, one time the same day when we worked for the same company.
It hasn’t always been smooth, but SO MUCH BETTER than working for anyone else. And now DH can throttle down and work fewer hours as he wants.
I retired after 26 years at the same company. It’s out of the norm today, but I only worked for 3 companies - 2.5, 3, and 26 years.
