Hi
@tesolo welcome to the forum.
Have you tried taking another of your sims into CAS on your home lot? If you do not have another sim in that particular household it may be worth quickly adding one just to try this out.
Sims do occasionally get stuck at work but usually they come home eventually often without the ability to control them. Scrolling out until your mouse cursor turns into a magnifying glass and traveling often solves this too.
Also if you use mods take them all out while trying to solve this, often glitches like this are caused by out dated mods and/or cc.
