I've been back at work for one month after 12 month's maternity leave, and I'm already thinking about leaving. I've got an interview for another job tomorrow. The usual notice period is 4 weeks but I was wondering if there is a longer notice period if you've taken a year's maternity leave? Is there a statutory obligation or is it just down to the individual employer? My employer has never mentioned anything about this to me so can I assume that I'm free to leave the job as normal?
