What is one supposed to do in this situation?

When you get hired somewhere, it’s probable that you’re going to have to make some adjustments on entry. You never truly know what a job is going to be like until you’re two feet in, and then you probably already have something to lose. The person in this story was starting at a new job and didn’t quite realize what it would have in store for them until it was too late. The way they saw it, they were trying to fit in at a new place of work. The way their employers saw it, they wanted continuous service for their customers, but with a strange twist. 

It never looks good when a company has a lot of turnover. You probably assume that something is amiss with the job when they’re always hiring a new person for the same positions. Companies generally try to avoid this, to varying degrees of success. If you treat your workers well, you should expect to keep them. If you’re not, then they might slip through the cracks before you even notice. But if you’re hemorrhaging employees, the least you can do is be honest about it. To the people you work with, and to the people you serve. That’s what was going on here, but the employer was being sneaky about it.
