This study examined the effects of EFL teachers' behavior on intermediate L2 learners’ WTC in English. To this end, a proficiency test was administered to 150 female learners, and 98 intermediate learners aged 16 to 26 were recruited as the participants. Subsequently, a WTC questionnaire was distributed among them to measure their level of WTC. Moreover, interviews were carried out with 30 volunteers who agreed to participate in this phase of the study. The results of the analysis of the WTC questionnaire showed that the WTC level of the learners could be rated as above-average. Besides, the results of the interviews revealed that different kinds of teachers’ behavior affected learners’ WTC both positively and negatively: teachers’ sense of humor and rapport could positively affect learners’ WTC; on the other hand, teachers’ methods of error correction while learners’ speaking and teachers’ lack of support could negatively affect learners’ WTC. Additionally, according to learners’ perspectives, there were a number of ways through which a language teacher could increase the learners’ WTC in English such as encouraging learners to read extra-curricular topics and highlighting learners’ strengths instead of their weaknesses. Several implications were proffered at the end of the study to heighten the awareness of L2 teachers, teacher-trainers, and language institute managers regarding the issue under investigation.
