How are you going to take on the UX suffering without using the service?

You may still be hurting yourself more than you hurt them. I say may since I don't know your circumstances, but I am missing out on communications from my employer since they insist upon using WhatsApp.

Then it's your employer that's hurting you, not you yourself.

I agree since they should not be using WhatsApp for internal communications. The problem is that they do not see it that way since it adds additional hurdles with respect to communications from their perspective. That is especially true since I am the only holdout and few people seem to know how to use the organization's email system with any degree of proficiency.

Is that a company-wide policy or just between eg. you and your team? Which country?

It is between the team and it is in Canada.

EDIT: Just to add, the employer does not have a policy for communications between team members.

Is the mobile device issued by your employer? Seems like a pointy-hair layer problem otherwise.

The account would have to be linked to a personal device, otherwise I wouldn't regard it as an issue. (Only the team lead is issued a mobile device.)
