Donna is a welder with Rodgers Construction Company. She leaves for work in the morning and arrives every day at 6:45 am even though she starts at 7 am. She makes sure she is wearing her reinforced work boots, and has her welder's jacket, helmet, and gloves to keep her safe on the job. She focuses on her projects during the entire day. She does not typically leave early, but if she needs to, she talks with her supervisor in advance of that day. This is an example of what trait of professionalism?
