在工作日上学用英语通常表示为"to attend school while working"或"to study while employed". 这个说法来源于结合两个动词"attend"(参加，出席)和"work"(工作)以及名词"school"(学校)，来表示在工作期间还在接受教育。
下面是一些例句：
"John has been attending school while working full-time to further his education."
(约翰一直在全职工作的同时上学以提高他的教育水平。)
"She is committed to balancing her job and school while working towards her degree."
(她致力于平衡她的工作和学校，同时努力获得她的学位。)
"It's not easy to attend school while working, but he is determined to make it happen."
(在工作日上学不容易，但他决心要做到。)
