Thanks for your thanks MissSunny.
I'm being honest all our trainees and new intakes share rooms. Everyone who complains or comes up with any excuse to not share, other than a disability, is immediately marked as a troublemaker.
Whilst you may have the job you still have the probation to pass....
I wouldn't ever pay to go to compulsory training and a decent assumptive chat asserting this will normally be fine.
It is becoming in many areas standard to bunk people with each other on training or on initiation to the company.
Accept it and see how it goes.
