Engaging with new employees needs to be at the forefront of your hiring process. It is hard enough to retain top-tier talent in a competitive job market as it is, so making new hires feel at home is of paramount importance. The most effective way to do this is to put together a comprehensive onboarding plan for them to get acquainted with. This is the quickest way to get new hires up to speed on all of the important things, such as procedural and operational practices, as well as the smaller things that have a big impact on morale and productivity such as office culture.
An employee handbook is a requirement for any business, even small to medium, informal companies. While you're not legally obligated to create one, having all the rules written in one place and going over them with each new employee can help reduce misunderstandings -- and even lawsuits -- if there's a problem in the future.
