OP..
Be mindful on how you talk to people at work. If you have good rapport with the women at your job, then you have more liberty on what you can discuss, non work related speaking...
But, try not to get into any arguments because you already know whose side HR and management will take when it comes down to reprimanding folks.
Lastly, if you are working in a mixed environment, understand that certain groups of people have a tendency to be hella sensitive and are known to snitch. They will NOT hesitate to tell on you, so be mindful of that as well...
Lastly, if you think that you are on the cusp of getting fired, then the last thing you should be doing is engaging in insignificant banter with co workers and focus in your job, especially if you need said job to support yourself. Remember, self preservation comes first! Everything else takes a backseat ..
