Meaning:

In Japanese, sha (社) is from kaisha (会

社) and it means corporate, chiku (畜) is from kachiku (家畜) and it refers to a domestic animal. Therefore, shachiku means “corporate slave.” These people work a lot and prioritize their company’s interest over their private life. However, their hardwork is not adequately compensated, as this term often refers to low-rank employees, not workaholic company officials. This term originating from Japanese has caught on among Chinese netizens with “Weakest Beast,” a TV series starring Yui Aragaki as a dutiful company employee.

Example:

A: 今晚有空出来玩吗？

Jīnwǎn yǒukōng chūlái wán ma？

Hang out with me this evening, will you?

B: 我要加班。

Wǒ yào jiābān。

Sorry, but I have to work overtime.

A: 这周哪天你有空？

Zhèzhōu nǎtiān nǐ yǒukòng？

When will you be free this week?

B: 哪天都没空，我是辛苦的社畜。

Nǎtiān dōu méikòng ，wǒ shì xīnkǔ de shèchù。

I don’t have free time this week. I’m a poor corporate slave.
