Hi
I worked in Market research for 20 + years. I started in DP and then moved on to Research exec (quant), senior project manger and finally Associate Director. I worked primarily in quant, designing research projects and interpreting results.
I was made redundant about 18 months ago from a job where I had been alloed to work part time (first 3 days a week then 4 days a week) after having ds. However once I lost that job ( the company went under) I found it nigh on impossible to find any sort of part time job in the industry again.
The working from home seems to be mostly qual reserachers who often freelance. Freelancing as a quant researcher is more difficult as you need to have a base of clients to contact and work with as a starting point.
If you are looking to get back to work again you could trysome temporary contracts. There is a company called stopgap that does thes for the MR industry. However be prepared for long hours and full time contratcs (though probably short term).
As you may remember agency work tends to mean long hours in order to meet cleint deadlines. If you want to control your hours more, going clientside would be better but these jobs are hard to find withiout real business experience. I would try and use stpgap to get some work experience and maybe
Alos the MRS run courses so maybe attending some to get back in touch with the current work pracices would be good, though possibly a bit expensive to fund.
Finally online research has had an explosion in the last 5-10 years and if ytou can see any way of breaking into thavt let me know!
