> They only serve to make a manager feel like they know what everyone is doing, all the time
This is a cynical view of 1:1 time. I've always felt like a 1:1 is a time to bond with my manager, and look out for my own needs so I can make the most of my career.
Today I am a manager and I can hand on heart say I am at the service of the people I support. I am not telling them how to spend their time, I am not trying to know everything they are doing, I am there to listen, assist, and fill in organizational gaps to keep things moving and keep ICs unblocked.
Engineers are smart people perfectly capable of outthinking me, they are relied on for keeping their own work on track but to ask for help (maybe in a 1:1!) when they need it.
My work is done when everyone is happy and productive, 1:1s help me do my job and my job is to provide support, advice, consultation, and communication between the business and my team. I don't know how I could possibly make sure everyone has what they need, is working toward goals they care about, feel valued and heard, without regular 1:1s. If I were an IC and my manager didn't check in with me regularly I would not feel like I was part of something, managers help glue teams together because no one else on the team is going to do that.
