Ephesians 6:5-9 ASV

When reading this text, it seems to me that, while we don't have slavery any more, this could easily apply to an employee/employer relationship in just the same way. Don't slack off when your employer isn't watching. Work with enthusiasm. Work for your boss sincerely as you would if you were working for Jesus Himself. Employers, treat your employees the same way - don't be harsh with them and treat them with respect. Sounds like this passage does translate well to the modern era afterall...
