In an office full of people, chances are you're going to have to sign a birthday card every now and then. And if you're a perfectionist, that can be stressful. There are so many elements at play—you want a message that's cute, but not too cute. Something a little more creative than just “happy birthday!” but something that isn't flowery, either. Don’t worry! Perfection is possible.
Because we feel it is our sacred duty to make your life a little easier, we've compiled a list of funny, sweet, and even sentimental birthday wishes suitable for any colleague relationship. There's even a section of birthday wishes for your boss, because whew, we all know how complicated *that* 'ship can be.
Feel free to take any of the below and add some fun details to make 'em a little more personal. That said, it's probably a good idea to avoid mentioning that time they got too drunk at the office Christmas party or the fact that they hate their job—you never know where that card might end up, lol.
Okay, now that we've got a handle on that, go forth and navigate office social politics with confidence!
