Is it because you need to fill a gap in the team skillset? Is it because you need expertise in a function? Are you hiring because you have too much work to do?
Or do people keep talking about growth and “more people” is what you think growth is?
Are other people getting promoted because they have bigger teams and so you’re making a bigger team?
Is there an initiative that you think is necessary but maybe you’re having a tough time articulating why to your colleagues?
From a business perspective there are good reasons to hire and bad, and some businesses incentivize the bad (inadvertently or not).
It isn’t always your fault when you hire for the wrong reason, but that doesn’t mean you shouldn’t have your eyes wide open about it.
