ELI5: The Verizon workers going on strike

My understanding is that it is an economic strike. So I asked a friend of mine who works at Verizon "why not just quit?" They have hired temps to fill those positions and I could be wrong but because of the nature of the strike when it's over doesn't mean they also have job security. I was told clearly I don't understand picketing or collective bargaining. Although isn't picketing or strike a result of collective bargaining not working in the first place?

Edit: thank you all very much for clearing that up for me.

The issue is the value of a temp worker who can fulfill a task over the short term, and the striking workers who have training and experience in their jobs.  While Verizon (or any company, really) can simply fill-in for striking workers with temps, or by pulling from other divisions of the company, the replacement workers won't be as good at their jobs as the striking workers.  Or, at least, that's the principle.

The idea behind a strike is, at its most basic, to convince a company that they need the employees, and need to meet the employees' requirements to continue effective operations.  So no, a strike isn't a result of collective bargaining not working, at least not in the sense you may have meant it - its a tool to make collective bargaining viable.
