There are a few challenges to taking a sabbatical leave. These challenges include: 1. Finding a way to cover your workload: While you are on sabbatical, someone else will need to cover your workload. This can be a challenge, especially if you have a demanding job. 2. Staying connected with your colleagues: It can be easy to lose touch with your colleagues while you are on sabbatical. Make sure to stay connected with them so that you can easily transition back to work when your sabbatical is over. 3. Coming back to work: It can be difficult to come back to work after a sabbatical. You may have to adjust to a new workload or to new colleagues.
