The Chartered Institute of Personnel & Development (CIPD) have reacted with dismay at plans to shelve these rights.
CIPD chief executive Jackie Orme said: "This news is spectacularly ill-timed for hardworking families struggling to balance work and family responsibilities, and plan budgets that include substantial childcare costs."
She added: "Government assumes flexible working is a burden for businesses and a charitable extra that can be cut back in tougher times. The reality is flexible working can deliver competitive advantage by improving employee engagement and attracting talented people to organisations that otherwise might remain outside the workforce."
Orme argues employers need motivated part time and flexible workers to survive tougher times.
