Comment Never EVER Absolutely EVER Work for free. (Score 1) 716
Period, no matter what do not do work for your employer for free. Do it once and you've set a precedent that you can't undo.You pay me to program machines to make parts for you, you are also paying me to make the normal number of mistakes and fix them. If I screw up so often that you can't live with my output, then I should find a different job, if you expect me to fix my mistakes for free then we are violating the basic premise of my employment. What's more you will have created a situation where your employer has a financial interest in making you work for free, and they will accordingly seek to maximize their profit by getting you to do so at every opportunity, the situation will grow worse with time and you will hate your job. I have done something similar to this in the past and it lead to a nightmare scenario. (Although I was exempt salary so it's hard to say when I was working for "free" exactly)
When you have made a mistake you might be tempted, but don't fall for it..
As other posters have said a company or contractor repairing something for "free" for it's end customer is fine, those costs should be, in the long run cooked into the price of doing business, but if you are a regular employer you should never ever do this under any circumstances.
