Update on work messing my schedule up

Started a new job from hell and they email you the schedule. I got the email, responded that I got it. Then I got another email saying it was updated - several hours were removed. My other way to check my schedule did nlt update - and they kept calling me. I refuse to answer calls and keep a paper trail first, but yeah they messed it up.

When I showed up for that shift, they had someone else scheduled for it as well. I showed this coworker the written email - with the shift and sayimg this was correct - so we both clocked in and worked together.

Beware of these jobs calling. The email trails are for your own protection.
