将下面一段英文翻译成中文：I’m a full-time white collar worker. I should say my working conditions are really good. The working hours are very reasonable. I work 38 hours a week, from Monday to Friday. I get a four-week holiday with pay. I always go on a two-week vacation in the summer and I usually take another week to travel abroad in the winter. Then still leaves a few days if I want to take time off for something. We’re even allowed to take an unpaid leave if it’s really necessary. Our company introduced a flexible working time system last year. I can start any time between 8 and 9 in the morning and sometimes can leave as early as 4 o’clock in the afternoon.
