There’s a belief that changes to holiday laws will benefit employers. 

The Government's drafting legislation to change the Holidays Act 2003. 

It'll include proposals to pro-rata sick leave and move annual leave from an entitlement system to one using accrual. 

Employers and Manufacturers' Association's Alan McDonald told Mike Hosking that an accrual system is favoured because a single calculation is needed. 

He says employees will know what they're getting from day one, while employers just have to do the calculation and get it right. 

But Unite Union Assistant Secretary Gerard Hehir says that the changes will affect many Kiwis. 

He says over 40% of employees work part time.
