What are your experiences?
Sadly, much the same as you. For me it's not a new phenomenon. This has been my experience pretty much throughout my entire working life! I worked in an industry that was continually being squeezed, so there were continual threats of redundancy as the business contracted.
There are very few decent people managing teams. Out of the 7 or 8 companies i've been employed by in 29 yeas and the 250 odd different locations i've worked in, i'd say this style of manangement is pretty much par for the course. I've met a few good people, but not usually one's that I have had to report to. WHen you get a good manager, it's bliss.
They don't need to be nice to you, you are only there to make them money, end of. What you have to learn is to keep schtum, shut out their bullshit and learn to appear not to respond to it too much.
I hope you don't get made redundant!
