No. For example, the employer does not have the right to require a female employee to wear clothes and jewellery considered feminine or make-up, when it comes to the services sector. Unless there are uniforms, the employer can require a generally proper look, but an employee cannot be expected to conform to gender stereotypes.
Furthermore, it is fair and supportive to treat a transgender employee as a representative of the gender he or she feels most comfortable with. This means that a transgender woman may wear a skirt in the work environment and it cannot be banned by the employer. Rather, it can be confusing both in the work environment and among clients, for example, when a transgender woman has to wear clothes intended for male employees at work. Therefore, the employer must not prevent a transgender employee from wearing clothes appropriate to his or her gender identity. Support from the colleagues is important for a person, so that an employee could be actively committed to work.
