I would just get an uber if my first bus doesn't show up. 11 minute drive should be like $15-20 uber which is probably worth more than being late to work depending on how much you make.

You can also use an app called "Transit" which I use whenever I take the bus. It shows you when a bus is going to come as other riders on the bus track it in real time (that are also using the app). If you were using the app you would know that the bus wasn't going to arrive (there wouldn't be a live timer for the bus).
