People got booted from my first place of work a lot - probably something like 1 in 5 didn't survive the probation period. The idea is to make the probation period long enough that the employee can demonstrate value. If they can't demonstrate value in that time period, they are let go. This was not the practice where I worked, but you could have different probation periods for different roles. So someone who is primarily focused on technical debt might have a longer probation period than someone focused on rapid feature development.
