This company only cares about their wallet.
If they can cut cost by demoting you and cutting your salary, they will do it. They will tell you how much you mean to the company, but they don't mean it.
You're on call for 24/hr, you almost never get time off.
Head office only cares about head office and not the buildings they run.
They ignore staff requests.
They see everyone as expendable.
I have seen building managers demoted because they were "too tenant friendly"
I have seen some really good workers screwed over by this company. If you don't want a headache, skip this company.
