Creating a contact for the employer field should be an option, not automatic.
This idea was originally posted in 2015 and again in 2017. I want to bring it back up. Having a new contact created when Employer field is used is not helpful for most. If we want to track a company due to the amount of clients, we use keywords or tag groups. This data makes the database messy, especially when you have multiple people entering and one person abbreviates and the other doesn't. We put the employer information in with the Job Title just so it doesn't create an additional contact. That is our current work around.
