For me the worst job would be to develop front-end stuff as the sole dev in a design company.
Imagine having to go to great lengths just to have everything done perfectly down to half pixels.

I've had to develop a couple of projects for an external design company and their lead designer was an absolute cunt about quarter pixels. I'm glad they fired him and working with them had become somewhat sane again...

Some things in front-end are either impossible or near impossible to get perfectly and nobody will pay for those wasted days anyway.
Oh and by the way: Please get rid of IE. I fucking hate it almost as much as my ex's mom.
