If you work job share or part-time, quite a lot of your time is spent finding out what's been happening while you've not been in. Thus it is that Katie's catching up with things over a cup of coffee with Lola when Doreen comes into the staff room.
"I don't know why you both have to be in here supping coffee. Shouldn't one of you be keeping an eye on the staff?" asks Doreen.
"I don't know why you and Julia both have to be on leave next week. Shouldn't one of you be keeping an eye on the operational management of the Library Service?" asks Lola.
Motherhood hasn't mellowed Lola any.
