Every profession hides some health risks. Some are clearly seen, others may show in long-term. The point is work shouldn't hurt no one, from blue collars to project leads.
For blue collars most obvious are physical strains during work, especially their lower back and feet (from standing upright and lifting things). Administration usually sits on desks for long and that have an adverse effect on abdomen, spine and especially neck. For project leads, job pain might mean stress, as they're constantly multitasking: talking on two phones, typing on keyboard and speaking to people, all at once.
Work shouldn't hurt can be communicated through posters around the office and/or hashtags to employees' electronic devices. This way messages can reach anyone in the company, not depending if they've tech-related jobs or not. Posters/hashtags are supposed to educate employees and stimulate their curiosity to know more. Example: hashtags "workshouldnthurt" and "dontrepeatthatmistake", showing the mistake on and the right way to proceed; with "Care to know why?" section providing the details.
How would you stage or advertise your hack?
Of course, "Work shouldn't hurt" hacks have to be targeted to their intended audiences, e.g. communicate how to lift a box properly to people who usually do this type of work, or how to avoid multitasking to those who are suffering from it. Although all hacks might be beneficial for everyone at the company, as they share insight on other's jobs. Posters are to be placed in locations such as rest areas, bathrooms, so employees aren't busy there and can take a moment to look and remember the hack. Hashtags are to be communicated on lunch breaks, before or after work time, so employees don't feel pressured to instantly check or skip it. With time, campaign could form a trend and gain many followers; also valuable lessons of work-related topics can be communicated in this manner, expanding learning beyond the "Work shouldn't hurt" and offering desired scalability.
