Penguin has introduced bikes for work in response to many staff wanting to cycle to the firm's central London office. It has also brought in a home computing initiative. Speaking at a session entitled 'How to achieve a sustainable work-life balance', Susan Taylor, group HR director, said 75% of Penguin's 1,000 staff are female and 20% of staff work part-time and 80% flexible hours. Penguin already offers childcare vouchers.
