That used to be the case with Printers,years ago, many jobs were advertised in the paper, not now hard to find a ad for the conventional offset printer any more, sign of the times ! (Ross, Printers Supply Agency)

If I nail them to the floor they can't move around too much! 

Hi. I am a qualified signwriter and are highly qualified in the trade. (A signwriter is one who uses a brush). I worked at a few businesses in Melbourne and found that I would get paid the same as a 1 year worker. There was no respect for my talent and found a lot of workers were afraid of my skills especially graphic designers who thought they owned the trade. I work hard and have been ganged up on and moved on. I contracted and worked for wages but could not get a good wage. I was told I was the best they have had but I had to move. Back in my own business. Cheers. 

This is  a catch 22 position for the employee who moves around, it should show on their resume. I for one would be reluctant to employ somebody whose record shows that they have moved around frequently. I suppose they would come with arguments about problems that forced them to move from job to job but the suspicians would remain about their motives.
