Advice on making complaint about Boss

[HerRoyalVagisty]

My manager is married to a member of the team I work within. There is(and has always been) a strong "us and them" divide between the the team -them, boss, wife and a couple of her peers and us, the smaller admin side. Morale is very low among the admin, boss is utterly unsupportive, his wife is a trouble-maker.

I don't want to give too much away for fear of outing myself...but this is what happened last week.

Myself and admin colleague were "told off" by another colleague for talking, even though we were discussing a serious work issue. This kind of thing happens all the time, we are constantly undermined. I apologised to colleague (one of "them") but said I was unhappy at how she spoke to me. She stared at me, shocked and then turned her back on me. No further discussion.

Boss returned to the office shortly after and then his wife went out to lunch. Five minutes later his phone rang. I sit very close to him and the room was quiet. I could hear his conversation. It was his wife, ringing to tell him all about the incident with me and the other member of staff. He played along, responding to her like it was someone ringing with a normal query or something "ok! Thanks for your call!" A few minutes later he asked the colleague for a quick word and the left the room.

I am fed up with this treatment and I see it as a form of bullying. I have been making notes of examples of their treatment to us and I think this phone call proves there is a bit of a conspiracy going on.

Surely it's totally unprofessional for his wife to call him about something she had no involvement in?

If I used this against him in a formal complaint would I have a leg to stand on? Would it just my word against his? What should I do? I work in the public sector btw.
