An interesting topic, in my view, for a youtube video. Well done. "To define is to limit" (Oscar Wilde). I could not find online a tighter definition of "psychological safety at work", and the impression is rather of a stance, or attitude, towards expression of views at work with a view to greater fulfilment and productivity than of the avoidance of harm per se. It is my understanding that in the UK the health and safety at work legislation addresses mental, not merely physical, harm; though obviously its efficacy is open to question and debate. For me, it is important also to note that the views Amy is espousing are value-laden and the fruit of a certain 'soil' (Harvard business school?)- directness is prized, expression (rather than deliberation, say) too, a placing of creativity and business goals over the value of respect for hierarchy. You might be surprised, Amy, were you to attempt to bring those values to the table in a workplace in, say, Thailand- at least from my short but intense experience of the kingdom..it takes all sort of materials to make a delightfully vibrant tapestry.
@David Burroughs - thanks yes, I agree with regard to what you say about 'fruit of a certain soil' and how that has influenced the language that describes psychological safety. I guess given the main focus towards 'successful teams' in workplaces it's understandable but I don't see the idea as limited as a consequence. There are many who are looking to apply the concept to areas such as equality, diversity and inclusion, the latter particularly being an intended focus of promoting psychological safety. Rather than that being a limitation I think it's a useful and significant 'expansion' of where the concept can be applied as achievement of a greater sense of psychological safety would seem to invite an increased opportunity for anyone who presently feels excluded, treated unequally, that they don't have their 'difference' in whatever form that may be, recognised, to have more 'space' to express themselves and their concerns and challenges, particularly of the 'status quo'. So much of the concept reminds me of the aims and practices of mediation and conflict coaching and I'm presently creating a video on that connection. Thanks for the comment!
