I got a written warning at my job for being a complete fuckup for the last couple weeks. The warning mentions that my performance will be monitored closely until August 3, at which point my contract (I'm currently on a year-long contract that ends in mid-August) will be renewed. However, as these things usually go, I'm most likely going to be under probation for the rest of the year since warning periods don't ever truly end.
Have you ever screwed up on a job and gotten a second chance? Were you a nervous wreck from that point forward?
