You must plan the time to listen to your team, whether it's a full team meeting or individual Personal Progress Interviews (both quarterly).
You must learn from them what is working, what isn't and what to do about it.
You must lead.
A leader is:
The custodian of the qualitative vision - what are our core values?
The instigator of the quantitative targets - where are we heading (and by when)?
The example of the standards of performance and behaviour expected - the beacon of light.
Leaders display compassion when it is appropriate and zero tolerance when it is necessary.
Of all of these, I regard zero tolerance as the most important right now.
It's your bus - people are either on it or off it - there's no half-on.
Better a hole in your team than an arse-hole. Every time.
