Call centres are pretty much constantly recruiting and many do have WFH/remote work. The work itself is crap but, what can you do...
Otherwise stuff like retail, food services, other customer service oriented roles. Sometimes out of term seasonal and/or tourism based work too.
There may also be one off things like working as an ambassador during a uni open day, manning phones for your uni's alumni funding drives, or supporting admin during matriculation week, which are uni specific.
