What does the speaker think of his working conditions? He thinks that the working conditions are____________

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. That still leaves a few days if I want to take time off for something else. We’re even allowed to take an unpaid leave if it’s really necessary. Our company introduced a flexible working time system last year, so I can start any time between 8 and 9 in the morning, and sometimes I can leave as early as 4 o’clock in the afternoon.
