Well said Krusty!
However, while there are morons Qing up to accept the garbage on offer by the usual suspects(insert JQ), this situation will continue.
At the end of the day, you can't blame any operator for offering shyte T&Cs if the same T&Cs continue to be accepted. It is a free market and an indicator that what is on offer is acceptable. Until such time that there are no takers for these positions, then and only then will employers be forced to up the ante.
Unfortunately, I do not see an end in sight on the downward pressure on T&Cs in my life time.
