This job requires a lot of emotional labour. We are civil servants at the end of the day, and some patrons have an expectation that library staff are meant to service every demand. For example, we provide limited free printing every month for patrons. However, half of the time the printing service doesn't work. Some patrons will literally take it out on staff for not making printing go faster (even though it's outside our control). This entitlement by the public runs counter to the fact it is a free service. You pay for the service you get; it's very entitled to demand more from a free service. Other times, they assume we have experience as a social worker; and somehow we are experts at government forms (e.g. disability benefits, passport applications, immigration documents). Some patrons get visibly upset we don't all posses a Bachelors in Social Work and the skills that come with it. There are moments you have to deal with vulnerable populations; they sometimes share traumatic stories of their lives. And it's emotionally draining to have someone trauma-dump on you; and you are expected to just listen.
It's important to take care of your mental wellbeing at this job. It can be quite difficult because you have all these expectations as a public servant. And yet, you are also at the end of the day, a library worker.
