I work on team of 5 people and the annual leave chart is already booked up for summer and there is no prospect of me being allowed to book any leave.
I jooined this team from another department 2 months ago, by which time colleagues on new team has already booked their summer leave.
Issue is that I need time off, even if just 1 week. Its for childcare, I'm not going away on holiday or anything. Just childcare. The general attitude at work is tough luck, not their problem.
So I'm left with no choice but to consider pulling a sickie. To make it believable it's need to start my sickness before school is out for the summer, rather than the same day or week. What kind of sickness can I have? Ideally to last a week maybe 2. Just till my sister can get here (she's travelling till 2nd week of August but has offered to come and help when back). Need a plausible sickness idea that doesn't sound too cliche or made up.
