I have a typical office job in a Western culture. My colleagues and I spend 99% of our work time with our laptops.
My manager forbids me to write emails. I'm used to writing emails if I want to have things in writing, e.g. for documenting purposes (so that I know what was communicated when), to bring some clarity and structure into some complex topics, and, of course, also as a CYA ("Cover your ass") strategy - this is an important function given that the work in my current team is frequently extremely chaotic, responsibilities aren't clear and I'm frequently told to do things which are doubtful to say the least. The manager hates that, he sees emails as escalations, he basically forbade me to write emails to him and other colleagues.
After talking to him at least 5 times in the last few months about an issue, I decided to write a CYA email despite this ban. It's a big important CYA! It was important information, which had relevance for both that manager and his manager, who I also CC'ed. But yes, it was clear for me that it could be understood as an escalation. Still, in the email I was super polite, super understanding and accommodating. Absolutely no accusations were expressed, just facts.
The manager was furious. Interestingly, however, he told me I had never raised the topic with him before. He repeated the assertion several times, so it wasn't like I didn't understand him. He honestly believes I had never raised the topic with him!
The last time I raised the topic was just last week. We communicate in a language which we both speak fluently, so it was unlikely to have been a misunderstanding.
Can you tell me what (communication) strategies can be used in this situation?
