Notes

ACE touchscreen question "How many years have you worked in your current job? (If you have more than one job please answer this, and the following questions on work, for your MAIN job only)"

The following checks were performed:

If answer < 1 then rejected
If answer > Participants age - 10 years then rejected
If answer > Participants age - 16 years then participant asked to confirm

If the participant activated the Help button they were shown the message:

If you have more than one 'current job' then answer this question for your
MAIN job only (ie: the job that you spend most of your time doing).
If you have been with the same employer, but have changed jobs whilst you
have worked for them, then only give the number of years that you have been
in your current job (not the number of years that you have been employed by
the same company). For instance, if you have worked as mail-room sorter but
then been promoted to manager of the mail-room, please give the number of years
you have worked as the mail-room manager only.
If you have changed employers, but have had the same job, please give the total
number of years that you have worked in that job. For instance, if you have
worked as a cleaner for 3 different companies, please give the total number of
years working as a cleaner.
