Daylighters are workers who manage to work two jobs during one shift. Sure, most of us wear many hats in our jobs, but daylighters actually perform tasks for two different businesses while physically present at just one of them. Some of these career jugglers perform tasks for their secondary job with the permission of their boss at their primary job, but most hide the fact from their employers.

上班兼职族（daylighters）就是指那些在上班时间从事其他兼职工作的员工。我们大多数人在工作中都要扮演很多角色，但上班兼职族却能在身处一个办公场所时完成两项完全不同的工作任务。有些兼职族是在得到老板允许后将兼职工作带到办公场所来做的，不过大部分都是私下瞒着老板进行的。

For example：

She says she is a daylighter. She works as a receptionist in a company and runs her online shop at work.

她说她是“上班兼职族”。她在一家公司做前台，然后在上班时间经营她的网店。
