Union Health System says it's laying off 150 workers by the end of the year.
The job cuts will be mostly support staff including positions at Union Hospital in Terre Haute, and Union Hospital in Clinton.
Union says the cuts are necessary to keep up with a rapidly changing healthcare environment.
Since the Affordable Care Act took effect, Union officials say they've seen nearly a 10% drop in overnight patient stays.
With decreasing stays, they've seen a drop in revenue.
Some of the employees already know their positions are being cut.
But, they say, more employees will be notified within the coming weeks.
