I’m a mid level dev in a team of three devs (one jr and another “mid”), but the other mid is super lost all the time and is pretty much useless.

I have to do all his work because he can’t seem to handle simple tasks. He’s taking the whole sprint to do stuff that takes me or even the Jr dev less than 3 days.

I have no idea how he managed to get mid position in the first place. I don’t have a problem in helping someone catch up, but I feel like I’m basically explaining technical stuff to my mom. Nothing seems to catch up on him.

I’ve already talked to my manager about him, but unfortunately we are understaffed so she feels it’s unsafe to get rid of him, but I’m starting to consider taking up the load instead of having to deal with him much longer. This shit is honestly stressing me out so much I’ve considered simply quitting.
