I work at ASDA (days) but my other half used to work nights. Its over Â£8 an hr and working nights everyone becomes a real community as there aren't really many customers about so you can have a laugh.y dream job at the moment is to work at ASDA preferably at George. ASDA is one of the best places around with products that represent a great value for money. They also sell great chocolate/cookies. Best supermarket chain around by a clear mile.

At the high end, non-union extras earn about $100 dollars per eight-hour day, or $12.50 an hour.or the 9th, 10th and 12th hours of a workday, you'll receive time-and-a-half pay. If the workday extends beyond 12 hours, SAG rules entitle you to double-time pay. After the 16-hour mark, the hourly rate for SAG extras increases exponentially.
