I got used (work-wise) when I did security work many moons ago, I would do any shift under the sun with this company, 12-hour shifts and sometimes even doubles (24 hours on the trot) I kept telling them I wanted a permanent site with a good hourly rate.
They kept putting me on a retail site at £3.50 an hour when other sites were paying around £4.00/£5.00 an hour, this retail site was a clothes shop in Princess Street, Edinburgh, and because I was good at my job and caught a load of shoplifters or deterred them the manageress there wanted just me..
I kept telling my area manager I hated the shop and wanted a different site with a decent rate but he did not listen until I put my notice in to join another company that guaranteed me a site with a good rate of pay, £6.00 an hour and I accepted it, on my last day the job I was already on the area manager kept following me around asking me not to leave and promised me another site with a better rate of pay.
I told him " You are to fucking late mate and you can stick your offer up the back of your arse, I would not trust you as far as I could throw you..."
The job I took was a site where I worked for 14 years and worked my way up from a security officer, security supervisor and eventually on the management team at the building where I retired.
