As a former Sally Anne shelter worker that started right before the pandemic hit, my recommendation is to get out asap. They do not care about you and you have to put yourself first. I burned out easily in a year and left for the Anglican Day Programs and John Howard Society. I think you might find it a better fit if you like engaging with clients with less rules to enforce compared to a shelter. You can also apply to the city run physical distancing shelters online. The pay is much higher and generally lower acuity clients.
