If the work uniform is not suitable for pregnant workers, you can ask not to wear it. According to the Law on the Protection of Women's Rights and Interests, any unit shall protect women's safety and health at work and labor according to the characteristics of women, and shall not arrange jobs and labor that are not suitable for women. Therefore, it is not necessary to wear work clothes when receiving pregnant in the hotel lobby.
