Never. Life’s too short to waste time doing something that makes you unhappy. That being said, um if you got bills... you better have a plan B.

Age? none. Responsibilities? Yes, could be an issue. The point should be to make and save as much as possible, but to invest funds into passive income sources so you don't have to depend on a job to make your main income eventually. It should be taught in school financial independance, but the issue with that is consumers will stop consuming the things the top 1% depend on them to buy. There is a reason for such a delta, population wise, between the top 1% and the rest. Just my opinion of course...

There is no age where it is unacceptable to quit your job.

There are no circumstances where is it unacceptable to quit your job.

Depends on what the job is doing to you, and your plans after you quit. The question is a bit vague.

It's always acceptable to quit. I think this is pretty field and timing dependent. In tech, people quit all the time for a variety of reasons. If the market is hot, it is easy to find another job. I've often been headhunted. When I was a senior manager at KPMG Consulting / Bearingpoint, I got recruited into Oracle as a director. In my exit interview, my senior partner told me to come back in a year or two and she'd bring me in as a partner.

If you are in a field with limited options, then you have less flexibility.

Hmmm. 54. I say this because of where i worked. You can retire at 55 and start to draw your pension. If you die at 54 and havent started your paperwork to retire... your wife will loose your pension. Even though your vested in retirement for a large amount of years... lets say 20.... if you quit or get fired before your 55... you loose it till age 55. Then you can draw 50 percent. This is were i worked.

Kinda weird question? Lol. I submitted my retirement last week though. True story. Gonna live that sweet pension life on the beach in my solar paneled RV.

im so confused...why would your age determin if you should be able to quit your job?

It is acceptabel at any age. Teh only difference age makes is tha as you get older, you probably need much better reasons to quit a job.

when you have enough money and had enough or have another job to go too unless you want to live on the street. you can walk out right now if so.

The Dark Ages.

I've never quit before.

It's never unacceptable to quit your job, regardless of age. Do what makes you happy. If you find that you dislike your job at any point in your life, find a new one!

Not enough information. Management job holders seem to be able to quit and go elsewhere without any loss of pay or benifits. Unskilled, semi-skilled and skilled (i.g. macinists, etc.), often are told that the policy of the new company (or in the case of a Michigan teacher) is to drop them on step/level pay wise when they are hired. So, in order to give meaningful advice, you need to give a whole lot more information. Note that in management, it is common for a company to hire a "head hunter" to "steal" away a manager from another company.

After you've given notice that you're retiring?

Other than that, people of all ages leave jobs all the time.

13, you should be in school !
