Low pay: 'I don't put the lights on'

Tracey earns £6.50 an hour, the legal minimum that employers can pay.

She tells BBC Scotland's Fiona Walker how she expects her electricity, paid by a meter, to run out before her next pay day: "There's a possibility that I'll be sitting on Wednesday night without anything.

"I don't put the lights on generally, at night. I sit with the light off."
