A Colleague Presentation About Your Sabbatical
A good way to reintroduce yourself to your workplace and any new colleagues after your sabbatical is to do a presentation.
We've all had to sit through endless photos (or worse still, slideshows) of some random relative's trip to see an ancient rock, so do not fall into the trap of thinking everyone will be enthralled by a monologue about your adventure.
However, a brief presentation that has been carefully planned can be informative, entertaining and a useful tool to illustrate what you have been doing for time away.
Ask PermissionBefore you start planning your presentation in any great detail, speak to your boss or line manager and ask if they are happy for you to talk to your colleagues about your sabbatical. Give them a brief overview of what you will talk about, make it clear that you will conduct the presentation at a suitable time (perhaps at lunch time or on a Friday afternoon) and that you will illustrate what you learnt that can be beneficial to your career and the company.
Once you have agreed with your boss or line manager when you are going to give your presentation, let your colleagues know. You could send out a group email informing them of the place and time - don't get too carried away with the formality of the invitation or you may irritate your colleagues and look like you are showing off. Just keep it friendly and say that on this date and time you will be giving a short presentation about your recent time in wherever and that everyone is welcome.
