When a job is listed as remote in the account, then it is not tied to a specific location. The person in the role is able to be away from the office and in a remote location.
You might not want to mark certain positions as remote if it's beneficial for that person to be in the office to fully understand the day to day. Some positions require knowledge transfer as well which is easier to do when they are in the office.
Please be advised that listing your job as "Remote" may also make it harder to find through the organic feeds Hireology partners with. We advise to always use a location whenever possible.
