• Find out where the spare toilet rolls are kept.

Especially if you are at a place with only a one cubicle toilet as the worst thing that can happen is that you are the last to leave office and need to have a dump and the toilet paper is empty and you don't know where the replacements are. Find this out within the first week.

• It's OK to be 'bullied' when you are new.

For everything that you do when you are new, you will learn 10 new things.
Just don't accept work that's supposed to be done by other departments on behalf of your own department.

• It's normal to feel everything is not going well and there are problems at every turn of your job.

Without problems, you wouldn't have a job.

• Be sincere.

Whether you are helping someone, receiving help, apologizing, praising etc.

• Don't bring negative emotions back home.

Keep your home a positive place.

• Don't offend secretaries, speak nicely to them.

They are generally nice people. They are important people. They keep the locks to the stationary cupboard. They decide the order in which their boss handles unscheduled things which is like.. EVERYTHING. From Purchase Requisitions, leave approvals, anything that requires a signature etc.

• Customers can shout and will be tolerated but that doesn't mean they are right.

I was an End User (in semiconductor wafer fab manufacturing). There were some people that shouted at the suppliers or vendors when things were not going so well and it was stressful. I was one of them. After awhile, I realised three things;
1) It felt good, real good that you can shout at someone because you were the customer (actually my company was) and things were going wrong and the person on the receiving end 'did' deserve it one way or another. But it NEVER helped solved a problem just by 'shouting'. It may put some urgency on the part of the receiver to get thing going but shouting alone never solved any problem by itself.
2) These people I was shouting at were businessman and experienced people in the industry while I was a young punk that happened to be the customer. Also they were driving big cars and I was taking public transport..
3) Most of the managers and directors didn't have to shout but they were doing their job well. It's hard to learn for some people, but I'm trying.

• There is no good time to resign.

Only the reason matters.

• Fully utilise your employee benefits if your company offers any.

Plan since the beginning of the year. Most people will see their unclaimed benefits expire at the end of the year and they don't roll over to the next year.

• Do NOT abuse your employee benefits.

This one doesn't need explanation.

• Do NOT quote me.

This one doesn't need explanation either.
