Jobs and tattoos depend solely on the employer and their written policies on appearance in the workplace. One establishment may overlook tattoos where another prohibits displaying them. In most cases, they simply need to be covered.
Can My Employer Fire Me for a Tattoo?
Employers are allowed to have grooming and appearance guidelines as long as they are fair and do not discriminate based on categories that are protected by the law such as age, gender, race, religion, disability, or national origin. The employer must implement a grooming and appearance policy with clearly stated standards as well as disciplinary actions for violators.
