'It wrecks my head' - Do parents get priority over single people for taking time-off?

There is an opinion piece by an anonymous person in the Daily Mail with the headline 

“Why I can't bear mums that snaffle all the Easter holidays, by a childless woman who's had enough of their selfish behaviour.”
