You may have noticed how some workers are kind of proud that they don't really do much at work. Proud to be a slacker is not a biblical concept. According to Proverbs a slothful worker, or a lazy worker, is as bad as someone who destroys things. How hard we work and if we are also fairly compensated for our work are both important to God.
[1 Timothy 5:18b] The worker deserves his pay. So wouldn't the opposite also be true? The worker who won't do his or her work does not deserve to be paid. It's very easy to reach the logical conclusion, if you are less than a hard worker (and getting paid full wages for it) you are being lazy and stealing from your employer.
