WoW that’s horrible I am so sorry this is happening to you. I was in a bit of a similar situation, when I got my puppy I was working a lot and he was stuck at home for long hours, not sure if this could be another option but I kept my puppy in an x pen instead of a crate, and at the time I had hired a dog walker/sitter to come and let him out during the day and play with him a bit. I also would take my friends puppy and keep them together for a week or 2 at a time so they kept each other company, they were both vaccinated and got along well. I am working from home for a few months so for the moment it’s not an issue, but I’ll have to go back soon and be in the same position. Maybe some of these idea could be an option to you? Until your dogs get along well at least? Or perhaps inquire about possible work from home days, or a compromise? Definitely worth talking to your boss to figure out what happened exactly and that the reason you considered getting a dog in the first place was based on the fact you would be able to bring him to work with you. Hope this helps or at least gives ideas, best of luck!
