Your work ethic follows you from job to job. So does the lack of one.

Habits of effort are portable in a way that job titles are not. How you handle the last twenty minutes of a shift, whether you check your own work, whether you need telling twice: all of it travels to the next place and shows within a week. Nobody gets a clean slate on this, because the slate is you.

Choose one standard you hold regardless of the job: nothing handed over unchecked, no mess left for the next shift, no phone while somebody is waiting. Hold it where nobody is watching, since that is the only place it actually gets built.
