《公安机关消防刑侦部门火灾调查工作协作规定》，对消防和刑侦部门对火灾性质认定存在分歧

High school students need “cool” jobs in summer holidays. Working at popular retail chains(零售连锁店) and ice-cream shops are good choices. The U.S. Department of Labor(美国劳工部) says that about two-thirds of the teenager workers are in fast food business. 1/5 of cooks and food workers are between 16 and 19 years old and 2/5 of food workers are part-time workers.

If you think taking a part-time job is easier, you are wrong. For young people, whatever you do, do your jobs well. Because a good work record will be useful for higher-paid jobs in the future. Let’s share my story.

Unless with my family members, I would go to eat fast food. That doesn’t mean I don’t like working in a fast food restaurant. My first part-time job, at age 16, was at the McDonald’s in Bloomington, Indiana. It was very hard work. Especially on Indiana University football weekends, we had no time to rest, but we still had a lot of fun. Finally I got a higher-paid job.

A future manager believes that difficult work encourages success. The growing U.S. population will bring more restaurants. While many people can’t deal with the pressure(压力) to fill orders quickly, the people who really do a great job will get plenty of rewards in the workplace.
