Yes, twice.
First time, we all had to have our picture taken for some reason, I can't remember what now. Some manager took mine, asked me to look after taking a couple. I said it doesn't matter which is used, I'll look just as bad in each, meaning I'm.not photogenic is at all etc.
The next day, I get called into the office, the manager is there, my manager and maybe someone else.
Said manager is apoplectic, going how she's never been spoken to like that in her life etc.
I cant remember the outcome of the meeting, but I called an agency and set up a job for the next day and walked out early.
The next time, I had 4 sites I covered and had to split my time between them all. I'd visit each one in order each day finishing up at the busiest one, where I spent the rest of the day.
All was well, until a girl, whose site had finished came to bide time on mine. Her dad worked in the company. That should have been my cue to start looking, as once a perm member of staff arrives, you on contract will be shunted out.
So, she arrived, then another woman from HO started coming to site, then started making an issue out of the number of hours I was billing for each week, as I wasn't on site for all of those.
Now this must have been deliberate because no one is that thick that they don't understand the hours I'm not at that site, I'm one of the others or travelling between them.
So, she creates such a fuss, they wanted to cut my money, so I walked that day, got something else lined up for the next day and never went back.
And that was at a pretty big, well respected, South East company.
