I've taken an extra year out after maternity leave finished due to losing my job, I'm looking to go back within the next couple of years and have started applying now. The gap would be between 2-3 years. How many years until an employment gap becomes a problem? I'm happy to stay off due to childcare fees, but I'm aware that a longer gap may be an issue and I need to be back at work by the time my youngest starts school and don't want to get stuck.
