Your knees may hurt after work due to overuse, strain, or poor posture during your work activities. This can lead to inflammation and discomfort in the knee joints. It is important to take breaks, stretch, and use proper ergonomics to prevent knee pain.
Please state why your knees hurt? Is it an injury? Is it arthritis? It makes a huge difference, so please rephrase your question.
As long as you keep their head above your knees, it won't hurt them.

Not necessarily. Of course, if you exercise improperly (such as bouncing at the bottom of a squat, in my opinion) you may injure your knees. Even assuming that you exercise properly, after several decades of training your knees may hurt a bit during exercise. This does not happen to everyone. If you always warm up properly and use perfect exercise technique, it may never happen to you. Exercise selection, too, is important. For example, it is a good idea never to do heavy leg raises because they really stress the knees. Even if your knees eventually hurt during training, there may be ways to work around it. For example, if regular back squats hurt your knees, switch to box squats. Box squats are much more difficult, which means that you will use less weight; using less weight means less stress on your knees.
Your question ... the way you wrote it ... really doesn't make sense. I think you meant the second choice to be "legs straight and knees locked". That configuration is more likely to hurt you, because your knees can't absorb any of the impact, and the shock is transmitted up into your hips and spine.
