Is this a joke? Job advert

I don’t think anybody gets proper premium rates for weekend or night working nowadays. When I started work in 1976, time-and-a-half on Saturdays and sixth days and double time on Sundays was fairly standard in most types of work. Now it might be a pound or two more but that seems to be all. I guess it’s all to do with the way weekends have changed in the public perception.
