It's going to be different depending on what team they are leading but there are some basics.
Getting written up and coached for things that would never have been mentioned before.
Being set up to fail, too much work with too few staff and hours.
Inspections after every shift with a list of failings.
They will coach you for eveything. For example if you were a CTL, they find an out of date, your coached, a vendor does not fill their location on a day your off, your coached, a week later they find an out of date, your coached, cleaning not done on a day your off, your coached, empty vendor spot, your coached, rinse and repeat for couple of weeks and your written up. Rinse and repeat another month and your on your final. Seen it happen many times. If the ETL does not play ball, they are also put through the same thing. Sure you can fight it and most likely win but, by that time you want out. Anybody who has been in the company for a long time knows how it works. And you can a super star for years and just one change of leadership can sink you.
