Calling work email a "resource" seems a little dubious to me. I.e. if I use office stationary to write my union manifesto, they have to buy more stationary. If I send an email they don't have to buy more of anything.
Especially in the world we live in right now - email and other work-hosted communications platforms are not a resource provided by work, they are the WORKPLACE.
