Fair question, I do it for my colleagues and my bosses have said they appreciate it. I also do it so I get paid - but not for the hours involved. It’s a very niche business and we all have to help out - unfortunately I am getting the brunt of it because of my experience and competency.
Then, with all due respect & with no ill will intended - who the fuck are you doing this for?
Obviously not someone that appreciates your efforts.
