I can’t think of many situations where being successful means you get to degrade the quality of what you are doing.
The problem is peoples egos and signaling.
I once worked at a company and did this huge set of projects on a shoe string using creativity and hard work.
A manager was hired in another parallel group to mine and they got to immediately hire six people.
It made me so annoyed because it felt like I had demonstrated results and not gotten resourced.
It sets off these ego driven hiring wars.
Once one manager starts staffing up, you immediately felt threatened and under siege and at war.
If your competitor peers (they are never your friend) out hire you, then soon their people are coming into your area trying to take over work under you.
The entire thing is super corrupt. Like I personally don’t like over hiring but if you have never felt what it is like to be put in that position - it is quite threatening.
It also signals if you don’t hire the way other teams are hiring they you are a failure as a manager or as a team.
After this experience I realized how compromised you are being middle management: you lose skill and value and you become at the mercy of impossible to control politics coming from all directions.
And then what happens next? Well, many times the hiring manager who built their little empire leaves and dumps all the people they hired loose. They all end up in a sort of limbo. Original manager had an idea of what to do with them, now someone else ends up having to baby sit them, often without any vision for what to do.
This process of hiring and leaving just degrades the talent and dead weight: it’s such a sort of baked in disease and hard to get rid of.
I personally won’t be a middle manager ever again. At least not one that doesn’t report direct to a ceo.
