You are right. People need to know when they’ve got it good and to put their livelihood at risk at a time when there are no viable alternatives is a folly.
But we still hear of executive excesses (e.g. M&S) and management using the economic situation to exploit the workforce (e.g. unpaid internships). I’m afraid the Victorian mill owner instinct for exploitation is never far away! Unions still have a role in protecting workers in this environment. An eternal struggle in which the balance of power shifts with the prevailing economic and political environment.
