Max AB has some valid points, the idea of joining a company and fostering the collective will to better T's & C's is excellent. Its all about bettering the workplace and ensuring people stick around so nothing malicious about that.
Irregardless of the 'economic crisis' there is a race to the bottom mirroring some other industries and linked back no doubt to government policies that will not slow anytime soon. Companies can take advantage because there is still the 'demand', requirements will be dropped as the pool shrinks but T's & C's won't necessarily be lifted in order to stimulate demand in times of weak supply.
The reality is that people join organisations for a multitude of reasons. The idea that if you don't like what is being served up then you should bail is at odds with the safety culture we all try and fiercely foster and protect. Fight the good fight I say, the race to the bottom will end at some point but by doing something about it there is the possibility of shortening and maybe even reversing its trend.
