Why would you fix errors on weekends? (except for critical stuff, and then take off a weekday instead, of course).

Errors are a normal thing for human work, especially software developer. Nothing you are "guilty of" and have to make right with your own money/time (same thing).

I was twice on weekend in the office in last 3 years: one time due to legendary IDE migration in the middle of project. It wasted 7 months in total. Any the other time I wanted to finish my release on time. Of course, it was postponed on Monday. Both times it was wasted personal time, zero gain.
