Egregiously poor management at all levels.
The most ineffectual, inept HR department of any company I've worked for in over 30 years.
Staff are very poorly treated.
Senior management rarely speak the truth.
Does not comply with employment law unless you shove the relevant legislation in the face of management and the HR department.
The company caused me an injury due to their admitted negligence; they refused to pay me for the time I was forced to take off due to the accident. They tried to put me on various stages of absence management, requiring me to get the GMB Union involved to get this overturned. The company offered me less than the legal precedent amount in damages, refused to pay more, and I had to take them to court; the judge found in my favour.
