いくつまで働くつもりですかって英語でなんて言うの？

Well if you ask someone in a working situation when they plan to retire, it may seem that you think they are no good at their job, or are waiting for a time when you personally may fulfill their role. So intonation and timing would be very important in this case.

In the United States there is no fixed age for retirement, and people retire at different ages. This is a direct way to ask that isn't rude. I hope that this helps :)

Retiring is when you get to a certain age and don't have to work anymore but get a pension in the UK this is 67 years old now People might think they are not wanted or no good at their job if you are asking them about retiring so it's best to ask politely and in a nice way

Sometimes people will never retire or never want to retire. You can even ask if they "Plan on retiring." asking if they will ever retire or just work until they can not anymore. Both of these examples ask the question you want to ask.

To retire, is to reach a certain age, as usually specified within law, that a person is no longer legally required work. To ask someone when they are 'thinking' about retiring, is an informal and polite way to ask them when they would like to stop working.

It is always good to remember to first get to know the person you are talking to, before you ask a personal question. Some people might find it offensive if you ask them the question about retirement but whilst other people will be okay with it. So it's good to be friendly and have a nice conversation with the person, if he or she is someone you don't know. If it is someone you do know, then the question will not matter. If you want to ask the question to a fellow colleague, be mindful of how you ask the question because your colleague might think that you think or feel that they are too old for the job or that you are asking the question because the company might be cutting down on staff.
