Terrible. Like many firms these days, they want you to work till 5.30. Two reasons for this; 1. If you finish at 5pm, you're likely to start getting ready to leave at 4.45 and therefore they believe that working time is being lost. By making you work till 5.30, they get more work out of you. 2. If you work till 5.30, you start thinking about traffic and how it'll take you longer to get home as it's peak rush hour time. So, you think to yourself may as well work till 6, when the traffic starts dying down. This makes your working day longer than what it should be. Really cruel psychological trick just to ensure every last drop is worked out of you for as long as possible.
