"My coworkers are great."
Translation:Meine Mitarbeiter sind toll.
I was told that in Germany nowadays it's a bit of a "gender war". Saying just "Liebe Kollegen" to address both genders can be seen as sexist, so people would say either "liebe Kollegen und Kolleginnen" (or just "liebe KuK", for short in writing). Some would also go to the other side and say "liebe Kolleginnen" instead to show men how does it feel to be excluded.
