And then because of salary compression and inversion where new employees at the same level as your former junior developers get paid more based on market trends while HR won’t give your former junior developers raises, they end up leaving when ther get “good enough”. So why hire juniors at all instead of poaching a mid level ticket taker from another company? If you are a line level manager, even if you want to retain your former junior now mid level developer, your hands are probably tied.
