Everyone has the right to freedom of thought, religion, and conscience, the right to respect for private life, and freedom of expression. In public life, everyone can choose to dress in a certain way, to keep their hair dyed, uncovered, long or short, to cover their head, to shave or to grow a beard, as a result of their religious obligations, political ideology, or preferences regarding their appearance. If an employee wants to keep her clothing and appearance in the workplace, her choice of appearance will extend to the working life. In working life, employers impose certain restrictions on the appearance of employees for many reasons such as ensuring neutrality in the workplace, fulfilling the needs of the work, workplace, or business, and fulfilling the requirements of occupational health and safety. One of the most common restrictions is the prohibition of an employee to grow a beard in the workplace. If the worker refuses to cut his beard even though the beard is prohibited, a conflict arises between the employer's right to manage and the worker's fundamental rights and freedoms.To resolve this conflict, the legal ground of the employee's right to grow a beard and the legal grounds on which this right can be limited by the employer shall be explained. Whether the worker's refusal to cut his beard can be considered as a reason for termination of employment relationship shall be evaluated and in this case, the type of termination shall be discussed according to each concrete case.
