働きます。

The word '働く' (hataraku - to work) has a long history in the Japanese language. It is believed to have originated from a combination of '機' (hata - loom) and 'らく' (raku - to operate/function), thus initially referring to the operation of a loom, a common form of labor in ancient times. Over centuries, its meaning broadened to encompass any form of labor or work. The 'ます' (masu) ending is a modern Japanese politeness marker, added to the stem of verbs to indicate politeness and, in this case, a declarative or volitional statement. The combination '働きます' (hatarakimasu) therefore indicates a polite statement of intent to work or the act of working.
