"Real" jobs?

The following is from http://money.canoe.ca/money/business/canada/archives/2010/08/20100806-084606.html
“Canada shed 9,000 mostly full-time jobs in July, nudging the unemployment rate up to 8%, according to government data released Friday. A 139,000 drop in full-time jobs was offset by an additional 130,000 part-time positions, Statistics Canada said. The results fell short of economists’ expectations of a 13,000 expansion.”
I beliee that part-time jobs have many disadvantages for the employee as opposed to full-time jobs:
lower gross pay (of course - fewer hour)
slower accumulation of seniority and related benefits (raises, opportunity for promotion)
absence of benefits such as extended health care coverage
less job security; if not outright lay-off, the employee’s hours can be reduced to the point where the pay cannot cover even basic needs
shorter-term entitlement to EI benefits if laid off
Many of the above seem to me to serve the employer well at the employees’ expense.
