This study surveyed bankers’abilities in terms of English listening and speaking skills using a total of 72 participants who worked in the Silom and Sukhumvit areas. The research instrument used to gather the data was a questionnaire. There were four parts to the questionnaire on listening and speaking skills: background information of the participants, the frequency of the use of English skills in merchant banking with foreign customers, their levels of ability, and their opinions on ways to improve English. The respondents filled out the questionnaires and returned them within a month. The data was analyzed using the SPSS program.The results show that the bank tellers were capable of listening and speaking skills at a moderate level. They improved their English listening and speaking skills, by taking English training courses for bankers in banks and other organizations, such as, a language institute. Moreover, they most frequently used English listening skills to give personal details and speaking skills for greetings, welcoming, expressing thanks, and saying goodbye. The findings may motivate bankers to further improve their listening and speaking skills in the future.
