Jim Murphy has pledged to call time on zero hour contracts to make work pay.
The Scottish Labour leader says his party will abolish exploitative terms and conditions and help families, if they win May's general election.
It's estimated approximately 84, 000 Scots have a zero hour contract.
The Scottish Labour leader said:
"In this May's election, Scotland can choose to end the scandal of exploitative zero hour contracts by sending Scottish Labour MPs to kick out the Tories and form a UK Labour Government.
"There are 84,000 proud Scots who are too often forced into zero hour contracts. Too many are left worried about whether they will have enough work and wages to be able to put food on the table from one week to the next. Many are blocked from getting credit they can afford and turn to extortionate pay day loans. It’s no way to treat people who want to work hard and get on in life.
"When working families prosper Scotland prospers, when people have decent pay and conditions they spend more and Scotland’s economy grows. That's the way to build a fairer Scotland.
"Too many Scots who want to work rather than be on benefit are caught in a cycle of poverty pay. They have no idea what they will earn from one week to the next. In 2015 too many Scots are still exploited for their labour. I am determined to change that once and for all.
"In May we can replace the Tories with a Labour Government who will ban exploitative zero hour contracts. The SNP had their chance to ban zero hour contracts last year and they let people down. It's time to bin these exploitative contracts once and for all."
