You usually stop by the supermarket or the gym after work before coming home. But yesterday you wanted to get home earlier because you are hooked on a TV show that you've been watching on DVD. You tell this to your friend.
I went straight home after work.
To "go straight to" somewhere means going there directly, without going anywere else on the way. Notice that you use "to" with most destinations:
went straight to work
go straight to the police station
go straight to my house
However, "home" has its own special rules. You shouldn't use "to" with "home":
go straight home
When talking about your job as an activity during your day, you should use the term "work" - not "my job", "my work" or any other variation.
I had an interesting coversation at work today.
She goes running in the morning before work every day.
