A Commonwealth Bank rule that employees must spend 50% of their monthly hours in the office is being challenged by a union in the Fair Work Commission.

The Finance Sector Union filed a dispute in the commission on Wednesday as the former Victorian premier Jeff Kennett was ridiculed for suggesting staff who work from home should be paid less because they saved money on travel.
