I just purchased a apple watch 3 and trying to set up cellular. However my plan is managed by my work and they are telling me they do not support having a cellular plan on the apple watch. Is it possible to have the cellular plan tied to my son's iphone but still paired with my phone?

Hi
No, I'm afraid that is not possible.
Apple Watch Series 3 (GPS + Cellular) has a built-in eSIM that copies information from the paired iPhone's SIM card.
The built-in cellular feature requires a carrier plan for your own iPhone that specifically includes support for the Apple Watch, including your carrier activating the device on the plan.
