John Gress / Reuters McDonald's jobs — like all jobs — provide employees with plenty of learning opportunities. McDonald's crew members shared what they've learned from working at the restaurant chain with Business Insider. The lessons ranged from treating everyone with kindness to learning to work with others. The food at McDonald's might be largely the same all over the world, but the experiences of its employees can vary quite a bit. Of course, the atmosphere of each store depends a lot on the customer base, the crew, the management, and the franchise-owner.
