John Smith is applying for the position of top R&D researcher for Glaxo Pharmaceuticals which has been working to develop a vaccine for Covid 19.

There are several other pharmaceutical companies also racing to get to market with a vaccine, however, the expertise needed in infectious diseases is unique and only a few scientists like John possess such capability. The President of Glaxo comes to you as head of HR and asks that an employment contract be prepared with John Smith and if we can include a non-compete clause in the employment contract. Please advise the President what elements would be necessary to have a valid contract and expand on the issue of non-compete with appropriate legal support.
