I thought the OP's meaning was obvious. It wasn't about the childminder. I interpreted it as "a job that I have to be physically present for and don't have much flexibility".
Since Covid and the huge increase in WFH, it does feel that some people have become fairly casual about work and that has fed through somewhat to the nannies/nurseries/childminders who care for their kids. Before, work was work and childcare had to be reliable. Now there is a view (which may be right in a lot of cases) that actually things are a lot more flexible. So parents at my DC's school don't take time off for school events, they just wfh that day and pop by for the carol concert or school play. And nannies are more blase about taking time off and nurseries sending kids home if they know that the parents are wfh because "it's ok, they can just work alongside the kids".
But there are some jobs where this isn't the case - they aren't flexible and you have to be there. Healthcare, teaching and (ironically) childcare come to mind, amongst many others. By "real job", I assumed the OP meant that she had one of these jobs and was being slightly pejorative about the other jobs which allow much more flexibility.
