Not all businesses need a hybrid system though.
Mine doesn't. Promotions don't really happen, you have to apply and interview for the next level up.
Also my team isn't even in one location, it's in 4. Spread across the country. So if we want a team meeting, we need teams anyway.
We've trained staff while wfh well and they are doing their job well.
We aren't customer facing either, ever. Its IT, but a specific part of it. We don't have customers. Plus anyone that we might need to talk to would likely be in an office not in our area, so again teams is needed.
A hybrid system is literally just the bosses wanting to see our faces, and yet they can't see everyone's so what's the point? Whether I'm in there or not they'll never know. Can go in for the days that they visit us, once a year if that.
Not everyone's place is the same. For some it will work, for others like mine it's pointless.
