Pay cuts

I work in a 4 star hotel I’v been there for many years now most of them good but recently they hired a new general manager and he has made cuts in every department people are losing their jobs their and he has recently cut everyones wages by 5% without any written agreement to the cut by any of us the moral is extremely low amongst the staff even before the cut the staff there work hard everyday to make sure our customers have the best time while they are there, none of the cuts are justified and he is also raising others wages while cutting ours along with hiring new staff. The staff there are angry and annoyed but feel like if we challenge anything we’ll just be fired for as long as i have worked there iv never seen the business this bad any review i read about it the staff are the main thing that are mentioned and from customers i have talked to both inside and outside of work if the staff stopped caring the business would go down. It seems like pure bully tactics that are in place right now theres no care for staff even after a horrific incident there recently that was witnessed by members of staff there was no concern for them at all they just seemed to worry are we liable for been sued or does our insurance cover us. To me it seems like theres just no point working anymore you just get shit on by managers and owners that only see money and not what brings customers in which is ho the staff feel when they work if the staff are happy people tend to come back more cause they felt that they were treated well i know theres more to it than that like the services the business offers but where i work those services are being neglected majorly and nobody seems to care. Theres nothing worse to me that cares about where i work to see it going down this path and i wish that somehow it will change but under the current management and ownership i highly doubt it will.
