Chances are that if, like me, you are interested in web design (or just design work in general) you probably already know about A List Apart, the amazing blog that has been a source of industry leading/changing ideas for well over a decade. If, somehow, you don't then stop reading this and start reading that.
If you need a good "jumping in" point, then I cannot recommend the article Defeating Workplace Drama with Emotional Intelligence enough. I realise I'm a little late to this particular post, given that it's over a month old, but ALA articles are definitely long form, so tend to build up in my feed reader between actual outings. Still, Brandon Gregory has hit the nail on the proverbial head in this instance. It may not be your standard A List Apart read (HTML, CSS or the ilk are barely mentioned... in fact I don't think they are at all!) but I imagine the advice contained would benefit anyone, no matter what industry you work in. I'll definitely be coming back to certain paragraphs for years to come.
