Would it not be better if they gave parents longer holidays?
In Norway you have to take a minimum of two consecutive weeks (out of 5 week allowance) every summer. Each family of two parents then usually end up taking 3 consequtive weeks. This way summer holidays looks like this.
1-2 week school club (or other arranged activity) 1 week with mum (or dad) 2 weeks with both parents (usually going away somewhere, preferably somewhere sunny) 1 week with dad (or mum), finally 1-2 week school club, then back to school, having had 8 weeks holidays.
The summer is the main time of year for young people or (long term) unemployed people to gain valuable work experience, as a seasonal worker, with a good rate of pay, and chances of being kept on.
