I vote for Friday morning of your last day. And spend the rest of Friday in HR making out the papers.
IMHO, you do have a strange view of your importance. A company is a machine to make money for somebody--and it is probably not you. It is not your family.
Working is like a poker game: if you haven't figured out who the sucker is in the first ten minutes, it is you. You owe them nothing.
I disagree. I have long-term friendships with some of these people. They have given me a lot of support and showed me a lot of kindness over the years. They have had my back; they have stood beside me when I needed them to; and they have helped me to grow as both a person and a professional. They have placed a lot of faith and confidence in me. I can't just say "F. you, I'm outta here." I owe them some notice, some advance warning, so they can make some adjustments to my leaving. I wouldn't want to end things in the abrupt way you're suggesting. It would leave a bad taste in my mouth. It wouldn't seem professional to me. I'd feel like I was being a d*ck to people I like and feel grateful toward.
I thought they would have a hard time replacing me, but what they did was to split up my job among several others, including one who was new and had nothing yet to do. ... Remember, in a good, effective organization nobody is indispensible.
I wonder if some people took my remark about my irreplaceability seriously. Humor gets lost on the internet sometimes. I meant the remark as a joke, tongue in cheek. I know I'm not irreplaceable. I don't harbor any illusions about that. I do have an odd, rather "niche" job, especially the way it is set up in my current workplace -- but there are several ways they could go about transferring the responsibility to someone(s) else.
Thank you, I'll read those threads for ideas, too.
Look at it another way. Has your company put any effort into succession planning? Have they sought out talented people, ensured that they have the required training, and encouraged you to mentor them? If not, that is their problem, not yours. Given that you have a niche function, give them the six months' notice, but once you have done so, do not waver.
No, the company really has not made much of an effort to arrange for a successor. There are various reasons for that -- lack of interested candidates, budget problems eliminating trainee positions; and the belief that I will stay until I am much older. You are right: that is their problem, not mine.
Good advice about not wavering, once I've put the notice in.
You are assuming that they will want to replace yourself with a clone of you. That might not be the case. When they selected my replacement he was the opposite of me. I was very hands-on. He was an administrator. Turns out management wanted to have contract workers do the hands on and the administrator administrate. Didn't do any knowledge transfer at all.
I don't think I'm assuming they'll want a clone of me. In fact, in some ways, I bet they will not. I am an introvert, and I just like to do the work and not bother with the social/marketer aspects of the job. They would probably prefer someone who's more extroverted and self-promoting in my position.
Have you considered transitioning to part time or some post retirement consulting with them? If so, that might be part of the transition plan but as others have advised, don't waver - these organizations will take all you are willing to give so you need to set boundaries and stick to them.
I've considered it, but my preference is to stop completely. I'm tired of the work. It's become pretty dull and repetitive to me. I'd like to just leave it behind and start a new chapter of my life. I'm concerned that if I stayed on part-time, I would still be tied there, with a little more free time but still immersed in that culture, still preoccupied with work stuff during leisure hours, still doing the same stuff. I'd rather move on.
It's been a good career. If I harbored ill will, I would have kept quiet and dropped a short notice. But, I don't have any hard feelings. I just want to get on with my life and things go smoothly for the one's that are left.
Yeah, that's kinda how I'm feeling, too.
