Very, very poor micro management.
They expect you to be at there beckoning call 24/7 out of your contractual hours, with no extra pay. A total disregard for the UK legal working time directive and Health and Safety. I'm not to sure how they have lasted so long other than cutting corners and abusing workers good will. At my time in the company I met some decent people some thought the same as I and some were just brain washed by the managment. Netomnia are just as bad as any other ISP out there. Very bad management, very bad working hours/conditions. I would be very surprised if they have not been to court over the WTD. My advise, avoid work here.
