tea breaks

Line managers sometimes shun team tea breaks. This is short sighted thinking. If a team of technicians or other lab staff spend most of their day separately, on their own preps/tests etc, there may be little chance to talk about non-work topics and gel as a group.
When a team are given the free choice to break when it's convenient for them and allow breaks to run on when they feel they need to, they'll be more likely to volunteer to stay late and get the job done when the work requires it.
Technicians are employed and paid for the process/prep/test, and as long as it gets done well and timely, there should be some give.

stock control

Often a technician will collect the items they need for a prep/process/test from a store, and shy away to small minded thinking when an item is nearly out of stock.

If supplies of an item are running low, the designated purchaser should be immediately informed, such that a mad flap over pieces of plastic is not necessary in a few days or weeks. The problem is mainly solved by vigilant operators.

A minor consumable, if out of stock, can suspend a process or more, and cause untold financial damage if a product cannot be made, both in sales and reputation.

Stock management is of little interest to the technician. It is a thankless task, is boring and requires an unnaturally anal and methodical mind to be effected well.
Poor stock management can cause a whole department to grind to a halt.

Expired reagents

Once a reagent expires, it should be quarantined immediately. It should be disposed of as soon as possible, to prevent it being used and causing a failed stock or process.
To simply make a mental not that it should no longer be used, without making it obvious to other operators, is less than acceptable.
Though one person knows not to use it, the next person to pick up the bottle may well be a different operator.
A physical barrier will prevent it from being used.

the wider view

A technician may become closed minded and think only of the processes he/she regularly does. The big picture can be left in ignorance and a blinkered view is formed. Though this encourages focus on the task at hand, and productivity in the selfish sense, it can be detrimental to the greater good of the department and company.
Even if a particular process is performing well, if the overall flow is impeded the work is for nothing.

problem solving

Problem solving is part of the core of a technicians job. A smooth process, task or test is what most wish for at the start of the working day. Complications and unavoidable plant failures will crop up and trample on this smoothness from time to time, and the lessons learnt during these times are what differentiates a good technician from an average one.
Over time, failures such as leakage in vacuum systems will occur and a technician builds up a repertoire of problems with associated solutions.
A great technician learns to apply the strategies and methods of problem solving to analogous problems, within the constraints of GxP and compliance with applicable regulations.
