Labour's original proposals were quite "radical left wing", but have been revised and will be quite different in the manifesto. Some say they have been "watered down" while others think they have injected a dose of realism or pragmatism.
The proposal to ban ALL zero hour contracts is now to ban EXPLOITATIVE zero hour contracts. Definitions are apparently still being discussed.
The proposal for ALL workers rights to apply from day one will now still allow a probationary period for performance. Flexible working from day one for all workers will retain the "except where it is not reasonably feasible" exception.
Ending "Fire & Rehire" practices is still policy.
Removing the age bands for the minimum wage is still policy, and they promise to tighten up rules on jobs with travel time (such as care workers who visit homes). They promise a "genuine living wage", but so do the other parties and none of the parties have given further details.
"Removing unnecessary restrictions on trade union activity" is still policy, but they have not said what these are or how far they will go.
They have said nothing about tightening rules on unpaid internships - a cynic might suggest that this is because MPs and the media are big users of this.
The original policy was to bring all these changes in during the first 100 days of winning the election, but I think they are backing away from this. If they win I think they will introduce an employment bill in some form within 100 days, but it will not contain all the final proposals - some will require further work before they become law.
