My husband has been doing his job for 7 years, he has always been good at it. He works in an office and updates customers files on the computer. Recently, a manager has really been picking at his work and checking everything he does in lots of detail, more than the usual checks. She has focused on his error rate, he was originally making 100 errors in 6 weeks. He was told he needed to cut it down to 20 in 12 weeks and was put on stage 1 capability. He has now cut it down to 25 in 12 weeks but has been noticed that the system is not working consistently and sometimes some of the changes he is making to files are not saving despite him clicking save. These are flagging as errors. He has pointed this out to his supervisor and manager but they are dismissive and say "I don't know why that has happened, it isn't happening to anyone else". Hes only managed to cut his errors down so much by rechecking files and saving them multiple times but this doesnt always work.
What can he do now? In his capability notes they haven't noted that he brought this up so now he is going to have to say that they aren't accurate.
They are completely dismissing that there is anything wrong with the system. He is not in a union as his contract says he isnt allowed (although i have insisted he is).
Im worried as im on unpaid mat leave and we have 3 babies...
