Workers at Fletcher Building and associated companies will be walking off their jobs this morning .

It's over a break down of pay negotiations.

First Union spokesman Jared Abbott said the workers voted to strike last week.

"Workers have elected to take strike action. It'll be about one hundred workers across five different companies and I would say that will last through later into the week including on Wednesday when Fletcher's will be having their annual general meeting."

He said the CEO received a 17 percent increase in pay up to almost $5 million, while the workers are struggling to pay their rent.

"You're talking about a number of different negotiations going on that have broken down for various reasons.

A lot of it does come down to pay but a lot of it is just the way Fletcher's has essentially conducted themselves."
