Avantages
Some of the people there are great. If you like sideways moves then it’s a great place to work, however progression is extremely limited and requires that you jump through several hoops or sell your soul to operations managers. My line manager did their best to try to make a bad situation bearable.
Inconvénients
I was essentially bought and sold with hundreds of other staff members to an outsourcer without any prior consultation or an offer of redundancy. The organisational philosophy is to micro manage you into complete and constant terror that you could lose your job at any moment. They achieve this using everything from monitoring and questioning how long you spend on pee breaks to constructing impossible quality assurance criteria. If you are moving internally, they will completely shaft you by insisting that they can only offer you a maximum 3% increase on your salary, while bringing in external hires at much better rates. They also make it a disciplinary issue if you’re found to be discussing salary with other staff members. Don’t take a job at Three unless you can guarantee perfect health for the rest of your life. You will be disciplined even if you’re declared medically unfit for work by a doctor. You will be expected to work every hour under the sun at their discretion with no consideration for any sort of work life balance - including a completely illegal 7 day working week. They will also refuse outright to recognise a union. If you want to work for a company that will allow you to actually use your holiday allowance rather than give you a number that you’ll never see, don’t apply.
