Lea probably mistook our dogshelter for a party hostel or Airbnb when applying as she didn't seem interested in our dogs at all. Like she says, working at a shelter requires a lot of responsibility, which we thought should go without saying. Unfortunately for both of us, it quickly became obvious that she is not a very responsible or dedicated young person. She went out drinking a lot and staying out till the morning slept through work or did her tasks very poorly the next day.
She also wasn't good at working in a team, having a confrontational attitude and on one occasion endangering another volunteer who just arrived. We always tell volunteers staying with us what to pay attention to for the safety of everyone, but this is not always enough and accidents can happen, unfortunately. You also have to actually pay attention and do your part as well, which was not the case with Lea. We trust that people coming to us are mature enough to understand this though, as they almost always are.
If this wasn't enough, she spoke badly about us to whoever would listen and was strangely nosy, asking inappropriate questions about our private life for no apparent reason.
As for not getting a goodbye, that's a bit difficult if you leave weeks before you were originally supposed to without telling us, but we'll be sure to work on our telepathic and clairvoyant skills.
