Which of the following actions can diminish a professional image?

Being dismissive of team contributions can significantly diminish a professional image. In a professional environment, collaboration and respect for colleagues' input are essential for fostering a positive and productive workplace culture. When an individual dismisses the ideas, efforts, or feedback of team members, it not only undermines their contributions but also creates an atmosphere of frustration and disconnect. This behavior can lead to a lack of trust and rapport among team members, adversely affecting teamwork and overall morale.

In contrast, being punctual and reliable, practicing openness and transparency, and actively seeking feedback on performance are all actions that enhance a professional image. They demonstrate commitment, respect for others, and a willingness to grow and improve, which contributes positively to both individual and team dynamics.
