一个概念的含义常被相对的概念所界定，因此要理解某一概念的实质，必须先理解其相对的概念。

Full time employment指的是：

...employment in which a person works a minimum number of hours defined as such by his/her employment... Full-time status varies between company and is often based on the shift the employee must work during each work week. The “standard” work week consists of five eight-hour days, commonly served between 9:00AM to 6:00 PM totaling 40 hours.

与之相对的概念是part-time:

A part-time contract is a form of employment that carries fewer hours per week than a full-time job.

据此，full-time employment可以翻译为“全时就业”或“全职就业”。Full-time employee可以翻译为“全时雇员”或“全职雇员”。关于part-time employment的翻译，除了“兼职”之外，如果想用……时来表达的话，就略显麻烦。有的词典里将其译为了“非全时就业”，但如果对就业的种类采取三分法，则就不太合逻辑。

比如：

An employee, including a shiftworker, can be hired as:

Full-time

Part-time, or

Casual

这里的casual，显然也属于汉语中的“非全时”：

A casual employee:

Has no guaranteed hours of work

Usually works irregular hours

Doesn’t get paid sick or annual leave

Can end employment without notice, unless notice is required by a registered agreement, award or employment contract.

因此，这三个概念作为相互对立的概念，翻译时，必须统筹兼顾，才能找到相互协调的翻译方法。Full-time译为“全时”、“满时”，与英文字面和意思完全对应，part-time可以换个角度，译为“减时”，这时part-time employment就是“减时就业”；casual employment看起来像中文的“打零工”，但中文打零工显然不是雇佣关系，而英文的casual employment在法律上还是雇佣关系，只不过福利少一些，因此可以按照其内涵翻译为“无定时就业”。

此外，需要注意的是，在日常语境中，full-time和part-time往往会被译为兼职，causal jobs也可指零工，并不一定存在雇佣关系，这在部分语境下也是可以的。

以下为相关双语示例，供参考：

The final requirement mandates the creation of full-time employment for not fewer than 10 qualified individuals。

最后这条要求规定至少要为十名合格人士创造全职工作机会。
