The president would be considered a white collar worker.
White-collar workers.
white collar-----> blue collar is labor work
Blue collar workers are laborers, especially factory workers. White collar workers are those who usually work in an office. The title of blue collar comes from the type of uniform that many laborers wear. The title of white collar comes from the type of linen shirt that is typically worn with a suit.
Receptionist, manager, and accountant are White-Collar workers
Generally, a white collar job is advantageous compared to a blue collar one because the blue collar job involves manual work, which is hard and time consuming, whereas in white collar jobs people are usually doing mental work since they are (in theory) more knowledgeable. Another advantage is that blue collar workers are often paid hourly and with lower wages, whereas white collar workers are often salaried and higher paid. There are more chances that blue collar workers are harrased or abused by white collar workers. On the other hand, white collar workers often have huge responsibilities on them.
People who are NOT white collar workers would be labourers, mechanics, gardeners, truck drivers, and such like jobs. 'White collar' workers would be clerks, bank tellers, librarians etc.
