You're not that important

Good teams hold the status quo when their manager is away.  Great teams take things to the next level.

Managers tend to (or want to) think that productivity and innovation halt the minute they walk out the door.  Truth is, if you've actively empowered your team (leadership built on mutual respect and a culture of constant professional development) then, well, you're the least relevant to the operation once they get going.

Things that should happen when you're away from the business without notice:

  1. Your senior team member steps to the plate and assumes much of what you do;
  2. Staff help solve each others problems;
  3. Opportunities for new business development, process innovations or improved efficiency are unearthed due to the slight re-org in responsibilities (these ideas should be given serious thought immediately upon your return);
  4. Partners, freelancers or internal departments write to tell you what a great job staff did in your abscense;
  5. Your clients don't even notice you're gone.

If things break down when you leave it may feel good to come back and gun sling things back into shape - but this only confirms you're the bottleneck.  Be predictive not reactive in your management style - your staff will appreciate it and perform accordingly. 

If your accountant, in particular, can tell when you're away then there's a problem.  It's you.  And you shouldn't be that important.
