My honest opinion: Without the union checking up on the employer, more horrible things would take place. Shame on leadership for gossiping, bullying, and allowing those in positions of power to get away with anything. Staff who work hard and care about the work they do end up suffering.
The history, racism and other problems with policing are not acknowledged or trained despite dispatch playing such a large role in how police choose to respond. Systems of power and abuse are perpetuated in a culture of white supremacy. Despite what they might try to tell you, this is not a safe place if you are: female, gender expansive, a person of colour, neurodivergent or anybody else outside of the criteria of "white male". And nobody in a position of power will admit that.
The work conditions are unrealistic and leadership will try to squeeze as much out of you as possible before you burn out. Take a look at the ever-growing list of stress leaves and resignations. It's truly shocking that this hasn't lead to meaningful change.
