On Friday you were one of the team. On Monday you're its manager, and the people who were moaning about the rota with you over lunch now report to you. This is one of the genuinely awkward transitions in working life, and pretending nothing has changed is the fastest way to make a mess of it. The relationships have changed, whether you acknowledge it or not, so you may as well do so on your own terms.
Reset the boundaries early and openly
Have the honest conversation rather than letting everyone work it out by trial and error. Acknowledge the oddness out loud - your team is thinking it anyway, so name it. Be clear that you value the friendships and that there will now be moments where you have to wear the manager's hat, make a call someone disagrees with, or keep something confidential that you'd once have shared. People respect that far more than a manager who pretends the dynamic is unchanged and then surprises them with it later. The first few weeks set the tone, and a frank early conversation buys you enormous goodwill.
Favouritism will sink you
The colleague you're closest to is the one everyone is watching. If your old lunch buddy suddenly gets the best projects and the softest deadlines, the rest of the team will notice within a fortnight and trust will drain away fast. Hold yourself to a visibly even standard - if anything, lean slightly the other way to prove the point. This is harder than it sounds, because the people you like are the people you instinctively help first.
Earning authority you weren't handed
A title doesn't make people follow you; it just makes them report to you. Authority is earned by making good decisions, backing your team in front of others, taking the hits when things go wrong, and being consistent enough that people can predict you. Do that and the awkwardness fades within a couple of months.
- Have a one-to-one with each person early to ask how they want to work with you now.
- Be transparent about how decisions get made so nothing looks like a stitch-up.
- One friendship may genuinely cool because they can't accept you in the role, and as painful as that is, you cannot manage by trying to stay everyone's mate.
You don't have to choose between being respected and being human. You do have to accept that the lunch table changed the day you took the job.
