ugh, can you imagine working with someone that takes a dig at you every single day! Every freeking day another dig, no thanks and I don't think much of either one for participating. I don't care who is "worse" than the other one. If I were the manager of such a fine station I would have put a stop to it YESTERDAY.
See, I work with lots of people who interact this way and it is understood to be joking banter. It's friendly. Is it a dig? Well, I mean, I guess, but it's not meant maliciously at all in my workplace. It's almost like non-sexual flirting. It surprises me that so many people take offense to it and think it is serious, actually.
Once its funny, twice its tolerable, but repeatedly its just mean. Jokes, IMO, should be positive things - I associate laughter with happiness. Digs can be funny when they are once in a while, but ultimately a "dig" is a negative, so when its over and over its not funny anymore because its not positive. It just makes me think the person making the digs is very unhappy and/or angry at heart and has no joy or positivity in their life.
Also laughing at digs, to me, is to laugh at
someone, not with
someone. It makes the target of the dig the punchline, not the wittiness of the joke.
If I worked in a place with this type of banter being constant I would consider it a hostile workplace.
