Sexual harassment is always a big deal due to it being illegal according to Title VII of the Civil Rights Act of 1964 - <a href="https:&#x2F;&#x2F;www.eeoc.gov&#x2F;eeoc&#x2F;publications&#x2F;fs-sex.cfm" rel="nofollow">https:&#x2F;&#x2F;www.eeoc.gov&#x2F;eeoc&#x2F;publications&#x2F;fs-sex.cfm</a><p>You will need to insure your company, employees and yourself are legally protected by visiting an attorney as soon as possible.  As it appears you do not have the standard company guidelines and procedures in place for investigating and terminating employees found violating law.  Your attorney should be able to help you draft the proper paperwork and procedures to accomplish this in your company policy and employee training.<p>When you talk with your attorney there may be more things that are required to do legally (filing a police report, filing charges, having the employee harassed file charges if she wants too, etc.).  The attorney will be able to walk you through everything you need to do.  As it may not be a big deal to your employee now, but that could change down the road, especially if it unfortunately picks up again or escalates.  Now would be the best time to resolve the issue while it is only at the texting phase, as things would go downhill for your entire business quick if it were to escalate in the near future.<p>I hope you are able to get this sorted quickly as it is very important to have something like this in a well known zero tolerance policy that everyone knows about on their first day on the job during their on boarding process.
