Are you asking whether glaives were used by infantry? If so, the answer is yes. Glaives and similar polearms in China, Japan, and Korea were used by infantry. Sometimes, they were used by cavalry (e.g., there is a section in the 18th century Korean military manual Muyedobotongji on the use of the woldo (a Korean glaive) on horseback), but this is unusual - they were predominantly infantry weapons. One example of one that was certainly made for use on foot: https://www.metmuseum.org/art/collection/search/21953

Are you asking whether glaives were used like spears? A lot of glaives are relatively heavy compared to spears of similar length, and will not perform the job of "long stick with pointy bit" as well as a spear. But that's not that they're designed for - a spear is mainly designed as a thrusting weapon, while a glaive is designed to be much more effective for cutting (compared to a spear). They will perform the job of a "long stick with cleaver plus pointy bit" quite well.

There are glaive-like weapons with heads like single-edged spears, which would be similar to spears in use. For an example in art, there appear to be some depicted alongside conventional spears here:

I don't know of surviving European examples of such small-headed glaives that are known to be weapons (as opposed to being farm or kitchen/butchery tools, which are sometimes socketed). There are Asian examples, such as the Japanese kikuchi yari (菊池槍), and some SE Asian polearms.
