Let’s get straight to the point. Yes, a dental hygienist can be an independent contractor, but if only he/she appropriately follows the rules.
Employers have a tendency to hire new talent and assume that the hard work is done. The truth is that onboarding a new dentist or dental hygienist is often just the beginning - the beginning of a long adjustment period, the beginning of training and assessment, and the beginning of all the paperwork, especially if you’ve made the mistake of relying on a turn-and-burn temp agency that has its bottom line in mind rather than your own long-term needs. After the placement agency fills your job opening, who has to deal with the results, whether good or bad? You, of course.
