Miliband Pledges To Tackle Zero-Hour 'Abuses'
Ed Miliband is promising to change what he calls the "worst abuses" of zero-hours contracts.
The opposition leader says a number of safeguards would be introduced to protect workers if Labour is elected.
The party's manifesto will propose a series of measures including legal rights against being forced to be available at all hours, and a ban from doing other jobs when no work is being guaranteed.
People working regular hours for six months would have the right to ask for a fixed-hours contract and this would be automatic after a year unless the individual opted out.
Compensation for shifts cancelled at late notice are also among the Labour proposals.
A recent survey found around 5.5 million people could be on the contracts, under which workers may not know if they have work from one week to the next.
The Government's own figures indicate they have increased three-fold since 2010, with their growth prompting trade unions to warn of a "growing sub class" of insecure, low-paid employees.
Mr Miliband is due to outline his plans to tackle the issue in a speech in Glasgow, where he is holding a meeting of his shadow cabinet.
He will point to the proposals as an example of how Scotland could lose out if it votes for independence.
Mr Miliband is expected to say: "Zero-hour contracts have spread like an epidemic across our economy.
"Sometimes, they can provide short-term flexibility for employers and employees alike.
"But we know most employers don't use them and for good reasons: the widespread use of zero-hours contracts is incompatible with building a loyal, skilled and productive workforce.
"And we also know a minority of employers are misusing zero-hours contracts as a crude way of cutting costs or managing staff.
"We'll put that right by ensuring employees who have worked regular hours get a regular contract.
"And by banning the worst abuses of the system like people being required to be on call all hours of the day for one employer without any guarantee of work."
And he will argue this would be harder to achieve if Scotland left the UK.
Mr Miliband will say: "If Scotland left the UK, the nationalists would compete in a race to the bottom: lowering taxes for the richest, lowering wages for everyone else, letting the banks and the energy companies do as they like.
"I will come here again and again ahead of the referendum in September with this message for the people of Scotland: by working together we can ensure that the Tory government in Westminster is just for one more Christmas.
"But independence would be forever; by working together we can change Scotland without you having to change your passport."
