Seems odd, the notion of probation periods in new hires. All most all of the positions I've seen offered in the past few years have been contract to hire, typically 3 months. Another difference here (in isolated CT) is we're a "work at will" state. An employer can terminate your job with / without cause. Just as I am free to say, "screw you" and walk out. Cuts both ways.

I know this seems odd to many people, but I prefer it.

If a master leads a man by a rope, then by that rope are both master and man bound. -Frederick Douglas

Do not make the mistake...of thinking that a worker is a slave and that he holds his job by his employer's permission. He does not hold it by permission - but by contract, that is, by a voluntary mutual agreement. A worker can quit his job; a slave cannot. -Ayn Rand
