Domestic cleaning jobs are generally advertised at around £6.50 to £7.50 per hour around here but people who advertise their services as cleaners seem to want £8 to £10 per hour. However this is very much a low-pay area. (I know a big firm that employs a graduate graphic designer, with post-grad training and several years experience, to head up their advertising team, at under £7.50 per hour. Indeed, many vacancies for experienced graduates here offer only around £7 to £8 per hour).
I've seen an advert for staff in a (fairly large) new shop. The 'ordinary' staff were just offered the minimum wage. The supervisors were offered an extra 2p per hour. (Don't spend it all at once, guys!!!) The manager's job (requiring him to be a keyholder, work unsocial hours and do all the book-keeping, including the VAT returns) was offered at a massive 10p per hour above minimum wage.
