While experience doesn't determine truth, my experience in the workforce (approximately 48 years) was that applying the principal of working as for God made my employer (or supervisors) happy with my work and garnered respect from them, while making me a subject of derision by coworkers (who still approached me for help when they were unable to perform assigned tasks.) This is generally what the scripture teaches us to expect when we attempt to live godly lives in this age.
While I agree that God saves us for good works, which will manifest largely in helping others needs being met, in the workplace, ministering to the needs of coworkers can sometimes put us at odds with our employers (who pay for our time.) I found in my own experience that my higher level of productivity made time to assist others, which probably lent itself to my employers gain, but they would have found more profit in having larger numbers of more capable or more responsible workers.
