I work for a small engineering firm and our work environment is casual--blue jeans, shorts, t-shirts, tank tops, flip flops, tennis shoes. In addition to the casual dress code, each employee sets their own hours with the only stipulations being that you must complete 40 hours per week between Monday and Friday and that the schedule you choose cannot be changed for at least two weeks. I work 7 a.m. to 5:30 p.m. with a half hour lunch Monday through Thursday and have a 3 day weekend. Having worked as a legal secretary for over 15+ years, in the 8-5, M-F world, this was definitely a great perk to my change in office careers. I've noticed that the atmosphere is more pleasant, morale higher and attitudes much better, which creates higher productivity.
