Very busy period at work, got email from colleague asking if I could do X thing, I replied and politely said I don't have time and could he ask (other colleague) to do it.
Next thing I get a reply to that but it was from MY manager! Anyway, it took a few seconds for me to realize, he must have blind cc'd my boss and that's why she replied to me... Felt quite WTF and annoyed about it, quickly followed by a feeling that they don't trust me and paranoia that perhaps this is maybe a "thing" and what other emails has my boss (or someone else) been copied in on without my knowledge?! Not that I send anything bad/dodgy but really, secretly copying in my boss on a regular work email? 
Anyone else experienced this? I've worked there for years and this is the first time I've come across this, It left a nasty feeling in my mouth.
