Before doing so, you need to carefully consider if you are subject to any restrictions such as non-compete, non-solicitation, non-dealing, garden leave and so on. In addition, during the changeover period while you are still employed by your existing employer and serving your notice period, you should be mindful that during this time, you still owe duties to your existing employer such as a duty to act in their best interests and a duty of confidentiality, as well as to comply with the terms of your agreed employment contract. In such situations, professional assistance is recommended to ensure that you do not trip up on any of your existing obligations and duties to your existing employer, while at the same time, adequately preparing for your next career move.
