Here are some examples of how it is used:
* 我每天早上8点上班。 (Wǒ měitiān zǎoshang 8 diǎn shàngbān.) - I go to work at 8 am every day.
* 今天我不想上班。 (Jīntiān wǒ bùxiǎng shàngbān.) - I don't feel like going to work today.
* 他已经上班好几年了。 (Tā yǐjīng shàngbān hǎo jǐ nián le.) - He has been working for several years.
It's important to note that "shangban" specifically refers to working in an office environment or a similar setting. It doesn't necessarily encompass all forms of work, like freelancing or self-employment.
