One time I got back from annual leave only to find out that my job had been done away with by the board over a year beforehand and my manager had spent the last year submitting fake timesheets claiming I was working a different position, so I could do the parts of her job that the assistant manager wasn’t already doing. The company had assumed I knew about it as they couldn’t get in contact with me when they discovered it and came down on the manager (my job was only the beginning of her fraud), but I was in the middle of nowhere and had no signal, so the first I heard about it was when I walked into the office and one of my coworkers went “what are you doing here?”.
