If you have a job at 900am and realize you won't arrive until 920am you would?

If I realize I won't arrive at my job until 9:20 AM, I would immediately contact my supervisor or manager to inform them of the delay and apologize for any inconvenience. I would provide an estimated time of arrival, and if possible, offer to catch up on any missed work upon arrival. Additionally, I would reflect on the situation to prevent similar occurrences in the future.
