Some Bad Habits

Introduction
Offices are complicated places with many varied interactions with other people; thus the need to behave appropriately, ie
"...Part of this is knowing what to leave at home. It's all well and good to be friendly and sociable, but is also worth discerning which things are okay to share with your mates at work, and which ones are not..."
Roselle, Umlas, 2023

Habits not to bring to work (8)

i) personal drama (need to remember that sharing your personal drama can make others feel uncomfortable; furthermore, they might think you're not capable performing your job because of all your troubles
"...you want to keep your personal stuff to the ones you're tried and tested - your true friends and family..." 
Roselle Umlas, 2023)

ii) intimate details (unless relevant to your workplace politics, like dating a co-worker, keep it to yourself; otherwise sharing intimate details can be seen as unprofessional.)

iii) health issues (these are sensitive and need to be handle delicately; only devolved health issues that will affect your work, some examples
        - hearing problems (otherwise people will think you are inattentive or even slow)
        - chronic fatigue or autoimmune issues they can leave you sluggish (otherwise you might be perceived as 'lazy' or 'incompetent')
Only disclose the information you feel comfortable disclosing; need to weigh up the pros and cons; need to be careful that you don't become vulnerable to unfair or differential treatment.)

iv) political opinions & religious beliefs (politics and religion are topics that can cause much division and conflict in the workplace; need to show respect for others opinions and beliefs, otherwise it is a recipe for disaster, ie
"...a simple discussion can easily spiral into fights complete with name-calling and invectives..."
Roselle Umlas, 2023)

v) financial struggles (discussing your financial situation can make other people feel uncomfortable; you can be perceived not being organised and/or not able to prioritise your needs, etc if in financial difficulties; unable to live within your means)

vi) inappropriate humour (the office is a diverse place filled with people coming from various backgrounds;
"...What one person considers harmless banter can be deeply offensive or triggering in another, so best to err on the side of caution..."
Roselle Umlas, 2023

stay away from using jokes like
"...- sexual innuendos or explicit sexual jokes
     - racial or ethnic jokes
     - gender-based humour
     - homophobic/transphobic jokes
     - religious jokes
     - ableism
     - ageism
     - body-shame in
     - political jokes..."
Roselle Umlas, 2023)
NB There can be legal implications of inappropriate jokes, comments, etc.)

vii) over-competitiveness (even though drive and ambition are desirable employee traits, they can be overdone and result in reduction in collaboration, teamwork, etc which are pivotal for performance)

viii) negativity (a complaining attitude; being a pessimist; this can lead to a toxic culture, ie gleefully point out other people's mistakes, etc; keep away from negativity)

Additional thoughts
"...The secret to being a great co-worker is knowing how to strike a balance between being friendly and keeping some aspects of yourself private. Ultimately, remember that while socialising is a big part of work life, the most important thing is that you're there to get the job done. So whatever you do, the professional and prove to everyone at work that you're an asset..."
