If you are employing staff, you certainly need to implement an Employment Agreement. This agreement should be between them and your business and it needs to be clear and well defined. This is because the last thing you want to happen is for your employee to get upset and then take legal action against your company for whatever reason. The best thing you can do is make sure each of your team is engaged using an agreement that both parties have read and signed and agreed upon.
Many times these types of forms are drawn up by lawyers. These forms can be very expensive and are not essential. It is only advisable for those who do not have time or resources to create this document on their own. A commercial lease agreement is different from a residential one. That is, renters have far more latitude such as constructing a building that suits their business but they have far less freedom in terms of what they can do with the property they are renting.
