You are not permitted to remove company documents from the premises. If you are the recipient of unwanted attention based on your gender, there are a few steps you should take. First, tell the offender that this kind of attention is unacceptable and that the behavior must stop. Be as firm and consistent as possible about your discomfort regarding this treatment. Second, you should report this behavior to your employer.
Many companies have specific procedures to address complaints of sexual harassment.
If your company has such procedures, follow them. Sometimes it is not possible to follow such procedures due to the nature of the problem. For example, if the company's policy is to take all sexual harassment complaints to your supervisor and your supervisor is the offender, then you should see if there is an alternative person to whom to report this problem. Finally, keep a record of specific incidents including dates, times, what both the offender and you said and did, and whether there were any witnesses. If the problem persists after you have reported it, you may need to take additional action, such as consulting an attorney or seeking aid from an outside agency.
