Work emails have to be “dumbed down” to get co-workers to respond.
If I send the fully detailed email I want to, explaining what the situation is, what actions I need them to take and why, I get ghosted 9/10 and have to waste time getting their attention.
If instead I send one sentence emails I can at least get a response and back and forth conversation going. The majority of my co-workers have difficulty parsing anything more than like 2 paragraphs for relevant info.
Like anything it’s nuanced. Defaulting to “They” when you don’t know someone’s preferred pronouns is generally fine, I don’t think many people have an issue with that.
Insisting that “They” is gender-neutral, or a catchall term and continuing to use “they/them” pronouns when somebody corrects you is where you’ll find people have a problem. Or in a similar vein, insisting that everyone can be referred to by they/them pronouns as a way of invalidating someones chosen pronouns and gender identity. (Not at all implying you do this, just examples)
