My work environment is 99% male - it is that type of industry.
The thing that I find hard to cope with is all the gossip and backbiting. It is shockingly bad.
The other thing is people cutting corners and not doing the damn job properly.
We work in rotating teams of two each day, and being paired with someone who will not follow the rules / protocols / is lazy is horendous for me.
I also made the mistake of confiding with someone senior about my concerns after a particularly tyring day...have discovered that the person I confided in is not trustworthy...and that my concerns have become gossip that has led to unnecessary discomfort.
I think retreating further into a protective shell is needed - no non-work conversations - and in future just ignore those who do the job badly.
I will focus on doing my part of the job properly and turn a blind eye to anything that is not going to jeopardise me.
