When I first switched from F/T to P/T back in 2001, I also switched to a mostly telecommuting arrangement instead of having to haul my sorry a$$ from Long Island to the office in Jersey City, New Jersey. At the time, I still liked the work and could do it from the confines of my own place. I did have to haul my sorry a$$ to the office once a week which was not fun but at least I knew after returning home that I did not have to go back there for another week. I also regained my personal life with outside hobbies and volunteer work.
In late 2003, my company did away with open-ended telecommuting. I could still work P/T but had to haul my sorry a$$ from LI to NJ 3 days a week to fulfill my hours. I knew at that time that this would become my eventual undoing, and I accelerated my planning towards an ER. This change also made it tough to maintain my outside activities when I telecommuted.
Besides the return of the horrors of a commute, even only 3 days a week, I also had to endure just being in the office more often. While I still liked the work (actuarial supervisor but with lots of computer programming, like an IT person within an actuarial division), that was beginning to erode over the next few years. By 2007, I could not stand it any more and asked to reduce my weekly hours from 20 to 12. This shedded one day a week of my lousy commute and got me out of the office at 5 PM instead of 6 PM, also helpful.
While it did ease my discomfort for a little while, it did not solve the problem - I still had to haul my sorry a$$ from LI to NJ more than once a week. The erosion of my liking of the work continued and the only way I felt I could solve this was to retire. By 2008, I was putting the pieces into place so I could retire. This included visiting a Fidelity advisor to make sure I wasn't missing anything. I had also been tracking a Fidelity bond fund (Focused High Yield) which could provide me with adequate income using the rapidly growing company stock (ESOP) in the retirement plan. I also found an affordable health insurance plan.
Once these pieces fell into place in late 2008, I gave them my notice and retired. I told the HR guy in my exit interview that I was sooo burnt out from the commute that even if they DID offer a resumption of the old telecommute deal AND allowed me to enroll in the group health plan (I was disqualified from it in 2007 when I switched to 12 weekly hours) that I would have rejected it anyway. The work I had at one time enjoyed was no longer enjoyable to me. The damage had been done. I had no choice but to leave and I do not miss the work one bit.
I can see how someone reading this might feel sad that something I once liked to do and got paid well for it was being rejected outright. I could very easily live on 12 hours a week. But the dang commute even two days a week was not just one day too many (versus my old telecommuting) but was now TWO days a week too many.
So I took the ESOP money (before the ESOP tanked for a while) and left. It generates nearly the same $$ as when I was working 12 hours a week!
No regrets.
